In the beginning of December I took my birth control for only about a week before losing the pack and just deciding not to take it anymore (my insurance has made it very difficult and annoying to get new packs). I started my period 2 days later as I expected because I stopped taking my BC (it was a week earlier than my regular cycle). It was just like any other period I've had. But now it's Jan 16th and i haven t gotten my period since then. I was supposed to start it on the 2nd. I did have unprotected sex (obviously haha) but my partner pulled out. And YES I know that's not 100% effective lol!. Anyway, I took a pregnancy test after the first 7 days of my missed period and then another one 2 days later but they were both negative. I plan on going to the doctor on Wednesday but I thought Id ask anyway, just to ease my mind a bit. This has never happened to me before and my period is always regular. 

Thanks in advance!
