Pregnancy Symptoms Soon After Sex

Early Signs of Pregnancy

While some pregnancy symptoms start very early, most of the time, you won't notice anything right away. Anything that happens immediately after having sex, like spotting or increased discharge, is usually not related to pregnancy.

Other than a missed period, pregnancy symptoms tend to really kick in around week five or six of pregnancy. This is about two weeks from when you missed your last period or six weeks since you actually had a period.

Occasionally you will hear of someone who has symptoms right around their first missed period. If you are hoping for or fearing pregnancy, it can be easy to ascribe any sensations to pregnancy symptoms.

Nausea immediately after sex is something that women question as a sign of pregnancy. However, your body doesn't have enough time to react to produce that symptom due to a pregnancy resulting from that sex act. Most women don't experience pregnancy-related nausea until weeks five or six of pregnancy. If you are having pregnancy-related nausea, you became pregnant weeks before.

Symptoms That Can Tell You If You're Pregnant Before Your Period

Having symptoms a day or two after having sex is usually not a sign of pregnancy. A pregnancy test is the best way to tell if you are pregnant or not, although you must wait until you miss your period to get the most accurate results. This can be a home pregnancy test or a pregnancy test from your doctor, midwife, or health department.

In most cases, you do not have to notify anyone of the test or the results.

Short of the world's most accurate pregnancy test, the best symptom that you can use is your taking your basal body temperature (BBT). This only works if you have been taking your temperature in the days prior to ovulation. The longer you have been collecting this data, the easier it is to tell what your pattern looks like.

If your temperatures stay high (above the cover line) you should assume you are pregnant until you know otherwise.

Why You Feel Pregnant

It can be fairly common as you enter into what many people call the two-week wait, the period of time between when you ovulate and when you expect your period, to experience some physical symptoms. These symptoms can include:

  • Feeling bloated
  • Experiencing mood swings
  • Increased number of headaches
  • Changes in appetite
  • Breast changes
  • A heavy feeling in the abdomen

While all of the symptoms could be pregnancy symptoms, they are more likely explained by either fluctuation in your hormones due to your menstrual cycle, or by other events in your life. These events can include illness, stress, or even something as simple as not enough sleep or too much exercise. Some women will experience premenstrual syndrome (PMS) symptoms as pregnancy symptoms, where other women do not typically have these symptoms every cycle. When you experience a symptom that is not common to your cycle, it may be easily confused with a potential pregnancy. This is particularly true when you are trying to get pregnant.

Not Trying to Get Pregnant?

If you are trying to avoid getting pregnant, it is best to find a method of birth control.

There are plenty of methods to choose from including condoms, birth control pills (oral contraceptives), intrauterine device (IUD), foams, Depo-Provera shots, and patches. Be sure to ask your midwife, doctor, or local health department for advice on the method that is best for you.
