How will I know if my diarrhea is severe enough to affect my birth control pills? #278/8

Sometimes food will not agree with me and I will have diarrhea a few hours after eating. I try new things a lot, and may have a sensitive stomach, but this usually happens at least once a month for one reason or another.  Every time, I freak out that my pill (Tri-Sprintec) has not been absorbed.  It is not particularly severe diarrhea, sometimes worse than others.

 
This means that my boyfriend and I can hardly ever have intercourse, because I'm worried that I've missed a pill and I'm supposed to wait 7 days before sex after a missed pill without backup.

How do I know if diarrhea is severe enough to be considered a missed pill?

I'm particularly interested, because yesterday I had sex and then had diarrhea a few hours after taking my pill. I took another pill just to be sure, but now I feel odd, as though I've taken too much (crying, etc).

Do I take another one tonight at my usual time?  And am I safe from pregnancy? I'm thinking of switching to a non-pill birth control to stop this. Any suggestions?


You ask: How do I know if diarrhea is severe enough to be considered a missed pill?

 

If a woman has severe diarrhea that continues for 2 or more days, she should follow the instructions below for missed pills.  However, it does not seem to me as though your diarrhea after a single meal is what I would classify as severe diarrhea.


Take your pills one at a time, not doubling up.  A woman can miss and entire day and her pills remain effective. You might want to consider a Mirena IUD.

 

 


MISSING PILLS

 

What can a woman do if she misses combined oral contraceptives (COCs)?

For 30-35 µg ethinylestradiol pills:

Missed 1 or 2 active (hormonal) pills or if she starts a pack 1 or 2 days late

  • She should take an active (hormonal) pill as soon as possible * and then continue taking pills daily, 1 each day.
  • She does not need any additional contraceptive protection.

Missed 3 or more active (hormonal) pills or if she starts a pack 3 or more days late

  • She should take an active (hormonal) pill as soon as possible* and then continue taking pills daily, 1 each day.
  • She should also use condoms or abstain from sex until she has taken active (hormonal) pills for 7 days in a row.
  • If she missed the pills in the third week, she should finish the active (hormonal) pills in her current pack and start a new pack the next day.  She should not take the 7 inactive pills.
  • If she missed the pills in the first week and had unprotected sex, she may wish to consider the use of emergency contraception.

 

For 20 µg or less ethinylestradiol pills:

  • If the woman misses 1 active (hormonal) pill or starts a pack 1 day late, she should follow the guidance above for “Missed 1 or 2 active (hormonal) pills or if she starts a pack 1 or 2 days late.”
  • If the woman misses 2 or more active (hormonal) pills or if she starts a pack 2 or more days late, she should follow the guidance above for “Missed 3 or more active (hormonal) pills or if she starts a pack 3 or more days late.”

 

For both 30-35 µg and 20 µg or less ethinylestradiol pills:

Missed any inactive (nonhormonal) pills

  • She should discard the missed inactive (nonhormonal) pill(s) and then continue taking pills daily, 1 each day.

 

*    If a woman misses more than 1 active (hormonal) pill, she can take the first missed pill and then either continue taking the rest of the missed pills or discard them to stay on schedule.

 Depending on when she remembers that she missed a pill(s), she may take 2 pills on the same day (one at the moment of remembering, and the other at the regular time) or even at the same time.
