I recently started taking Lo Loestrin Fe and for the first month did not have any sex at all (I'll mention that if I did, I would have also used a condom to be EXTRA SURE). Also during the first month, I had the "typical" breakthrough bleeding about halfway through my period cycle (right during when I would be ovulating). After my first month, I experienced very light spotting ("withdrawal bleeding") - all the usual. For this month, I started having sex without a condom, figuring the withdrawal and breakthrough bleeding were signs that the birth control had fully kicked in inside my body, along with the fact that I figured a month was a good waiting period anyways. At the end of my second back of pills, I did not have any withdrawal bleeding. I have started my third pack and had no spotting/bleeding whatsoever at the end of my second pack. Is this ok? Or should I be worried and getting a pregnancy test? I take my pill at nearly the EXACT time every night, but I'm remembering a two nights this month I vomited (not from the pill but other factors)... and I didn't think about the fact that might have counted as a 'missed pill'...
