Can I become pregnant on the last day of my period if my partner ejaculated inside me?

Answer 1

"In the proper environment, such as the female reproductive tract beyond the cervix, sperm have a life-span of up to five days. In other environments, such as the vagina, sperm live only a few hours and even less than that outside the human body, exposed to the open air. The egg, on the other hand, has a life-span of only about twenty-four hours from the time it bursts from the ovary. So, fertilization can occur anytime live sperm meet up with a live egg, which can happen even if the sperm are deposited up to five days in advance of ovulation."

"The monthly menstrual cycle is one of the key physiological functions of the female body. The average length of the menstrual cycle is 28 days, although 21 - 35 day cycles are common and considered normal or regular. The day bleeding starts is counted as the first day of a given cycle. The menstrual cycle is controlled by hormones released by the hypothalamus, the pituitary, and the ovaries. Each cycle has four stages: the menstrual phase, the preovulatory phase, the ovulation phase, and the postovulatory phase.

When menstrual bleeding has ended, the preovulatory phase begins. A hormone from the hypothalamus stimulates the anterior pituitary, which produces large amounts of follicle stimulating hormone (FSH) and small amounts of luteinizing hormone (LH). As the pituitary gland secretes FSH, which in turn stimulates the ovary, an ovarian follicle begins to mature. The ovarian follicle produces increasingly higher levels of estrogen. In response to estrogen stimulation, the uterine lining thickens with increased numbers of blood vessels and uterine glands.

In the ovulation phase at midcycle, the ovum (an egg) is released as LH production surges and FSH output decreases. The pituitary hormones (FSH and LH) that control the output of ovarian hormones (estrogen and progesterone) are, in turn, regulated by the level of ovarian hormones through a negative feedback mechanism. Thus, the increased level of estrogens depresses FSH production. Ovulation (the rupture of the follicle and release of an egg) occurs around midcycle. Some, but not all, women feel a twinge or cramp in the lower abdomen or back, sometimes with vaginal secretion, perhaps spotted or tinged with blood. This is called Mittelschmerz ("middle pain"). Following ovulation, the follicle transforms into the corpus luteum ("yellow body"), which produces the hormone progesterone. A few women have headaches, gastric pains, or sluggishness during this time, while others feel better — it's definitely an individualistic experience.

In the postovulatory phase, the secretion of progesterone begins to rise. Under the combined influence of estrogens and progesterone, the endometrium (the lining of the uterus) continues to develop and the uterine glands secrete nutrient materials. The endometrium is now ready to receive and sustain the fertilized ovum, if fertilization has occurred. The levels of ovarian hormones then remain high and the uterine lining is maintained intact through pregnancy. If pregnancy doesn't occur, the high levels of estrogens and progesterone gradually fall.

Below a certain level of hormonal support, the uterine lining can no longer be maintained and begins to slough off, initiating the menstrual phase of the cycle. The monthly shedding of the uterine lining that is accompanied by menstrual blood is called menstruation, or a period. As levels of ovarian hormones drop, their inhibiting effect on the pituitary hormones is lifted. FSH and LH production now begins to rise, and a new cycle starts.

Most women ovulate once a cycle about fourteen days before the next menses is due. However, women have been known to ovulate at any time during their cycle, including during menstruation, although this is unusual.

In terms of conception, fertility depends on three factors: a healthy egg, healthy sperm, and favorable cervical mucus. The egg lives for twelve to twenty-four hours and then disintegrates if not fertilized. Healthy sperm travel through strands of fertile cervical mucus, which is produced a few days before ovulation. In the presence of favorable cervical mucus, which guides and nourishes the sperm, they can survive as long as five days within the body. Otherwise sperm die very quickly and never reach the egg.

When estimating the fertile time, one can consider all of the signs that occur in the body. A natural birth control option, the Symptothermal or fertility awareness method, teaches women to recognize these signs. They include cervical mucus changes, feelings associated with ovulation, basal body temperature changes that occur after ovulation, and regularity of menstrual patterns. For most women, the fertile time begins after menstruation and ends with disintegration of the egg to the next menstruation. Calculating precisely when these events occur is impossible, but a close approximation can be made."

Answer 2

I think you are confusing ejaculate with orgasm. Most women can't 'ejaculate' as men do {and the ones that can are generally adult film stars]. Having an orgasm, however, relaxes the muscles in the vagina and 'coming' adds lubrication to assist the sperm up the canal. It's not nessesary, but it sure makes it a lot more fun!

Answer 3

They say you can, but I am having trouble getting pregnant on my "fertile" days. And I have 2 kids already so I know we don't have trouble in that department. I wouldn't stress over it, it isn't healthy for you, but you should be more careful if your not ready to have a baby.

Answer 4

It's possible. More so if your periods are irregular. Sperm can survive up to 5 days on the outside, and you might ovulate early.

Answer 5

It is highly unlikly. But it can still happen. If you are ovulating around when your period is, or if you ovulate up to about 3 days after your last day of your period (depends on when you ovulate!) then you can get pregnant. But if you ovulate nowhere close to your period, then you can not.

Answer 6

Yes, you can become pregnant at ANY time if you have sex. The only way to be sure to avoid pregnancy is to NOT have sex. The next best way is to be on the best, most effective form of birth control on the market and use condoms and spermacides. Don't have sex if you don't want babies. DUH.

Answer 7

Probably not, but don't leave that kind of thing to chance.

Answer 8

wow. heck yes.
best thing that works for me is abstinence

Answer 9

Not unless you're taking birth control pills.
.............And, don't you just hate that...........

Answer 10

YES YES YES YES YES YES YES YES, YOU CAN GET PREGNANT FROM HAVING SEX ANYTIME!!!!!!!
