I took my first pill one day late. Could I be pregnant? #903/7

I have been taking Tri Levlen for about 2 months.. My period was July 16, then on July 19th I was supposed to start my new pack.

We had unprotected sex on the 18th, and i forgot my first pill on the 19th until about 12 hours later!

Then in August I was on vacation, so I purposely skipped my period by starting a new pack.. Some pills were late, and we had sex. Now i've had sore breasts for about 3 weeks, a symptom I never ever have before a period! Do you think it's possible I'm pregnant?

You have been taking Tri Levlen for 2 months and your last period started on July 16th.  You had intercourse on the 18th and this intercourse was well protected.  A woman is protected during the days she is on placebo pills.  Am I correct in thinking you were less than 7 days from you hormonally active pills?

The timing of intercourse relative to your period and the manner in which you took pills does not place you at much risk of pregnancy, if I understand your history correctly. Breast tenderness occurs for some women on a cyclic basis and it may be that the changes you brought about this month caused your breast tenderness.


Thus said, pregnancy is always a possibility.


"Can I be pregnant?"

The answer to this for almost any sexually active woman in her reproductive years is: YES!


    • A woman can become pregnant even if she has taken her pills correctly.
    • A woman can become pregnant if she had had intercourse while still on her period ? even if she uses emergency contraceptive pills.
    • A woman can become pregnant using Depo-Provera injections perfectly.
    • A woman can become pregnant after having had tubal sterilization.
    • A woman can become pregnant after her husband/partner has had a vasectomy.
    • A young teenager can become pregnant before she has her first period.
    • A fully breastfeeding woman can ovulate and become pregnant in the first 6 postpartum months even if she has not had a menstrual period.


You get the point!  Reproductive age women who have

penis-in-vagina intercourse can become pregnant.


A home pregnancy test should be positive now if you are pregnant.  You should do this if you are still concerned.


            If there is any possibility that you are NOW pregnant and that you would carry your pregnancy to term, several recommendations:


If there is any possibility that you are NOW pregnant and that you would carry your pregnancy to term, several recommendations:

  1. Stop drinking at all if you drink alcoholic beverages.
  2. Go to a pharmacy and get prenatal vitamins, the most important of which is folic acid (folate).
  3. Make an appointment to both confirm your pregnancy and start prenatal care (if you plan to carry this pregnancy to term).
  4. Stop smoking at all, if you are smoking.
  5. Eat healthy foods?you will be eating for two people.
  6. Use condoms if at any risk for an infection.
