I'm on the BCP but....?

Question

my period is really irregular (been on it for 1.5 years)... i think the hormones of the others girls in the house are affecting it which i've been told can happen. Anyways, does this mean my BCP is less effective? I'm not having unprotected s*x(always use condoms), but accidents happen!

Answer 1

I'm not a doctor or anything, but I did a lot of research before, and after I first started the pill. The BCP is taken the first Sunday after your period starts, even if you're still bleeding. The way the BCP works is by inhibiting your ovaries from releasing eggs, as well as changing the lining of your cervix and your uterus (so that IF you do release one and its fertilized, it probably wont implant.) So, regularity or not, if you took your pill on the first sunday after your period, then you technically havent ovulated this month, and therefore, if youre taking it like you should (not missing) then theres little to NO chance of being pregnant. When you DO have your 'period' while on the pill, its not actually your period (IE expelling egg and uterine lining) but more of a pseudo-period. Blood, a small amount of uterine tissue, but nothing more than that, and you only bleed because a drop off in the hormones. Technically, you could skip over the placebo pills and not have a period for 3 months straight, though you would end up 3 weeks short before your next prescription.

Assuming you waited the 7 days like youre supposed to after taking the pill before having s*x (unprotected), and you take the pill at the same time every day (+/- 1 hour) you shouldnt get pregnant.

Answer 2

The birth control pill should help regulate your period so you know when to expect it.
