Is it OK to miss a interval while on birth control?
I'm taking Loestrin Fe, which is supposed to give you a four day spell, once a month, if it helps.
Answers: Yep. That happens to me every few months. I'm on indistinguishable pill. If you've been taking it at the same time every year and haven't been taking any medications which will retract out its effects (did you know that antibiotics will make your pill not work?) then you should be fine. If you're really worried, you can do a pregnancy question paper but you're probably all right.
