If you had an ovary and a tube removed, you can still be ovulating. (You presumably start out with 2 ovaries!) If one is removed, the other will still work as normal.
Ovulation is the process in the menstrual cycle by which a mature ovarian follicle ruptures and discharges an ovum (also known as an oocyte, female gamete, or casually, an egg) that participates in reproduction. Ovulation also occurs in the estrous cycle of animals, which differs in many fundamental ways to the menstrual cycle.
In the follicular (pre-ovulatory) phase of the menstrual cycle, the ovarian follicle will undergo a series of transformations called cumulus expansion. After this is done, a hole called the stigma will form in the follicle, and the ovum will leave the follicle through this hole. During the luteal (post-ovulatory) phase, the ovum will travel through the fallopian tubes toward the uterus, implanting there 6-12 days later if fertilized, or degrading in the fallopian tubes within 24 hours if not fertilized.
In humans, the few days near ovulation constitute the fertile phase. The average time of ovulation is the fourteenth day of an average length (twenty-eight day) menstrual cycle. It is normal and common for the day of ovulation to vary from the average, however.
Cycle length alone is not a reliable indicator of the day of ovulation. While in general an earlier ovulation will result in a shorter menstural cycle, and vice versa, the luteal (post-ovulatory) phase of the menstrual cycle may vary by up to a week between women.
Strictly defined, the ovulatory phase spans the period of hormonal elevation in the menstrual cycle. The process requires a maximum of thirty-six hours to complete, and it is arbitrarily separated into three phases: periovulatory, ovulatory, and postovulatory.
Through a process that takes approximately 375 days, or thirteen menstrual cycles, a large group of undeveloped primordial follicles dormant in the ovary is grown and progressively weaned into one preovulatory follicle. Histologically, the preovulatory follicle (also called a mature Graffian follicle or mature tertiary follicle) contains an oocyte arrested in prophase of meiosis I surrounded by a layer corona radiata granulosa cells, a layer of mural granulosa cells, a protective basal lamina, and a network of blood-carrying capillary vessels sandwiched between a layer of theca interna and theca externa cells. A large sac of fluid called the antrum predominates in the follicle. A "bridge" of cumulus oophorous granulosa cells (or simply cumulus cells) connects the corona-ovum complex to the mural granulosa cells.
Simply stated, the granulosa cells engage in bidirectional messenging with the theca cells and the oocyte to facilitate follicular function. Research is elucidating the specific factors used in follicular messenging at a rapid pace, but such discussion is beyond the scope of this article.
By the action of luteinizing hormone (LH), the preovulatory follicle's theca cells secrete androstenedione that is aromatized by mural granulosa cells into estradiol, a type of estrogen. High levels of estrogen have a stimulatory effect on hypothalamus gonadotropin-releasing hormone (GnRH) that in turn stimulates the expression of pituitary LH and follicle stimulating hormone (FSH).
The building concentrations of LH and FSH marks the beginning of the periovulatory phase.
For ovulation to be successful, the ovum must be supported by both the corona radiata and cumulus oophorous granulosa cells. The latter undergo a period of proliferation and mucification known as cumulus expansion. Mucification refers to the secretion of a hyaluronic acid-rich cocktail that disperses and suspends the cumulus cell network in a sticky matrix around the ovum. This network stays with the ovum after ovulation and have been shown to be necessary for fertilization.
An increase in cumulus cell number causes a concomitant increase in antrum fluid volume that can swell the follicle to over 20mm in diameter. It forms a pronounced bulge at the surface of the ovary called the blister.
Through a signal transduction cascade kicked off by LH, proteolytic enzymes are secreted by the follicle that degrade the follicular tissue at the site of the blister, forming a hole called the stigma. The ovum-cumulus complex leaves the ruptured follicle and moves out into the peritoneal cavity through the stigma, where it is caught by the fimbriae at the end of the fallopian tube (also called the oviduct). After entering the oviduct, the ovum-cumulus complex is pushed along by cilia, beginning its journey toward the uterus.
By this time, the oocyte has completed meiosis I, yielding two cells: the larger secondary oocyte that contains all of the cytoplasmic material and a smaller, inactive first polar body. Meiosis II follows at once but will be arrested in the metaphase and will so remain until fertilization. The spindle apparatus of the second meiotic division appears at the time of ovulation. If no fertilization occurs, the oocyte will degenerate approximately twenty-four hours after ovulation.
The mucous membrane of the uterus, termed the functionalis, has reached its maximum size, and so have the endometrial glands, although they are still non-secretory.
The follicle proper has met the end of its lifespan. Without the ovum, the follicle folds inward on itself, transforming into the corpus luteum (pl. corpus lutea), a steriodogenic cluster of cells that produces estrogen and progesterone. These hormones induce the endometrial glands to begin production of the proliferative endometrium, the site of embryonic growth if fertilization occurs. The corpus luteum continues this paracrine action for the remainder of the menstrual cycle, maintaining the endometrium, before disintegrating into scar tissue during menses.

For a lot of girls and women, there's no particular sign. I find that I might have a very slight cramping pain (similar to period pain but not so bad) and sometimes feel a bit .... ahem ....randier than normal.
I had a tube removed (although not ovary) due to an ectopic pregnancy about 12 years ago - and I was told by the doctor that the other ovary would worker harder to compensate for the loss. (Without the tube the ovary is pretty useless) Two years later I became pregnant with my son.
Are your periods normal? Failure to ovulate could mess them up a little bit.
Your best bet is to get one of those Predictor kits from Boots - they'll tell you whether or not you're ovulating.
Good luck x

You'd really need a Dr to tell you that ie tests.
However I had an ovary and tube removed a couple of years ago. Periods are totally normal and the Dr assured me that the remaining ovary "makes up" for the missing one.

Hi, you can chart your basal body temperature and cervical mucus to work out when (and whether) you are ovulating.
This links to an explanation of what to do -I think they have a chart you can download as well.

Sorry, about the name of the website if you're not trying to conceive! The info still applies, though.

Are you having a period? Have you been stressed out for any reason? Usually as mentioned before, breast tenderness, moodswings, bloating, sometimes cramping. I change in mucous discharge from your vagina, it is usually kind of watery, when you ovulate it thickens in order to create a plug if you concieve at that time.
