when is the earliest you can have symptoms of pregnacy?

Answer 1

The fertilized egg begins producing small amounts of certain hormones almost as soon as it begins dividing & multiplying. Sorry, I've forgotten all of the fancy terms for the process (oogenesis?), and the names of the hormones. Anyway, the little floating ball of cells is already causing changes within your body even before it actually implants.

Personally, I was usually pretty tuned into these changes due to using NFP, and being so aware of my cycles & symptoms because of that. I noticed little things, like bloating up right away, feeling a sense of congestion or fullness in my pelvis (blood rushing to the area to fuel the impending pregnancy), and on a related note, my heart would pump so hard I could feel it in my gut when I was laying down resting. This continued throughout the entire pregnancy. Within a few days of conception, I was usually peeing a little more often than usual, with a little more urgency (and less output, it seemed). Some pregnancies, nausea and fatigue hit practically from the moment of conception! Other times, it came along later, at the more "normal" stage of 4-6 weeks post-conception.

No two of my pregnancies were exactly alike, but those were the earliest symptoms I noticed in some of them. This was within 2-4 days of conception. HTH!

Pregnancy Symptoms — Early Signs of Pregnancy
Pregnancy symptoms differ from woman to woman and pregnancy to pregnancy; however, one of the most significant pregnancy symptoms is a delayed or missed menstrual cycle. Understanding pregnancy symptoms is important because each symptom may be related to something other than pregnancy. Some women experience pregnancy symptoms within a week of conception. For other women, symptoms may develop over a few weeks or may not be present at all. Below is a listing of some of the most common pregnancy symptoms. If you have been sexually active and experiencing any of the following symptoms it is important to take a pregnancy test. Find a Free Testing Center

Implantation Bleeding:
Implantation bleeding can be one of the earliest pregnancy symptoms. About 6-12 days after conception, the embryo implants itself into the uterine wall. Some women will experience spotting as well as some cramping.

Other Explanations: Actual menstruation, altered menstruation, changes in birth control pill, infection, or abrasion from intercourse.

Delay/Difference in Menstruation:
A delayed or missed menstruation is the most common pregnancy symptom leading a woman to test for pregnancy. When you become pregnant, your next period should be missed. Many women can bleed while they are pregnant, but typically the bleeding will be shorter or lighter than a normal period. This symptom is commonly explained by other reasons. If you have been sexually active and have missed a period, it is recommended that you take a test: Find a Free Testing Center or Order my pregnancy test

Other Explanations: Excessive weight gain/loss, fatigue, hormonal problems, tension, stress, ceasing to take the birth control pill, or breast-feeding.

Swollen/Tender Breasts:
Swollen or tender breasts is a pregnancy symptom which may begin as early as 1-2 weeks after conception. Women may notice changes in their breasts; they may be tender to the touch, sore, or swollen.

Other Explanations: Hormonal imbalance, birth control pills, impending menstruation (PMS) can also cause your breasts to be swollen or tender.

Fatigue/Tiredness:
Feeling fatigued or more tired is a pregnancy symptom which can also start as early as the first week after conception.

Other Explanations: Stress, exhaustion, depression, common cold or flu, or other illnesses can also leave you feeling tired or fatigued.

Nausea/Morning Sickness:
This well-known pregnancy symptom will often show up between 2-8 weeks after conception. Some women are fortunate to not deal with morning sickness at all, while others will feel nauseous throughout most of their pregnancy.

Other Explanations: Food poisoning, stress, or other stomach disorders can also cause you to feel queasy.

Backaches:
Lower backaches may be a symptom that occurs early in pregnancy; however, it is common to experience a dull backache throughout an entire pregnancy.

Other Explanations: Impending menstruation, stress, other back problems, and physical or mental strains.

Headaches:
The sudden rise of hormones in your body can cause you to have headaches early in pregnancy.

Other Explanations: Dehydration, caffeine withdrawal, impending menstruation, eye strain, or other ailments can be the source of frequent or chronic headaches.

Frequent Urination:
Around 6-8 weeks after conception, you may find yourself making a few extra trips to the bathroom.

Other Explanations: Urinary tract infection, diabetes, increasing liquid intake, or taking excessive diuretics.

Darkening of Areolas:
If you are pregnant, the skin around your nipples may get darker.

Other Explanations: Hormonal imbalance unrelated to pregnancy or may be a leftover effect from a previous pregnancy.

Food Cravings:
While you may not have a strong desire to eat pickles and ice cream, many women will feel cravings for certain foods when they are pregnant. This can last throughout your entire pregnancy.

Other Explanations: Poor diet, lack of a certain nutrient, stress, depression, or impending menstruation.

Answer 3

It all depends on the woman and the pregnancy. With my first pregnancy I knew when I was only 3 days pregnant. My breasts were extremely painful...even when barely touched. It even hurt to wear my bra. With my other two pregnancies, I didn't know for several weeks.
