Extra Period
chickie422 posted:
Just wanted to run this by folks to see if it's happened to anyone else, or if it's something I need to be concerned about. I'm 31 and have been on some form of ortho tri-cyclin for about 10 years, exercise regularly and eat fairly healthy. My period has always been very regular, but this month I experienced an "extra period" -- almost exactly halfway through my cycle, I got another period. Definitely was heavier than spotting, maybe slightly less heavy than my usual period. It started out brownish then turned to the usual dark red/brown combo. Then, I got my regular period as scheduled a couple weeks later.

Nothing was really different for me this month -- I'm kind of stressed out at work but nothing keeping me up at night. I've been in a monogamous relationship for over a year and my most recent pap smear (2 months ago) came back normal.

I guess these things happen sometimes, but since I'm on the pill I was surprised by the irregularity. Would love to hear any feedback! Thanks.

Dear chickie:Alas, breakthrough bleeding (BTB) can be a common side effect of most types of hormonal birth control (eg pills/patch/ring/shot/Mirena IUD). Among birth control pill users BTB frequently occurs after a missed or late pill. In your case it sounds like you are careful to take pills at the same time daily. More remotely, BTB in a pill user can arise if she has gotten a chlamydia infection. You both are monogamous so this is less likely. MANY other Pill users have written to us that they experienced BTB when under increased stress. Yet, there are no published studies confirming this--or offering a rationale.

When a woman uses hormonal birth control it can make the lining of the uterus more unstable--so it is easier to have some of it begin to shed. Sometimes the lining is less stable because the hormones make the lining much thinner (actually this is good as a thin lining is a healthy lining). In your specific case this would be more likely as you have been on the Pill for ten years. Sometimes the lining is unstable because the hormones can make parts of the lining out of synch. This is more common in the initial months of use.

Bottom line, BTB on hormonal methods of birth control is a nuisance side effect. The protection from pregnancy is still in effect. If your poor cycle control persists you should return to your GYN or clinic. Often a change in the brand, or formula, of birth control pill will fix the problem.

Thank you Jane! I figured this wasn't a big deal but thought I would check. You know, I did take a pill about a day late just before this happened. Usually I'm very good about taking it right around the same time every day but that day I was unexpectedly away from home. Maybe that's why my body was funky this month. Thanks again!
