I have an irregular period, I started taking progesterone for my period to make my period come.i had sex April 11, took plan b a hour after sex. I got a very light period(pinkish/red) april 29 and it lasted 5days.im not sure if I got my period from the plan b pill or the progesterone pill. I got my period may 31st and I expierienced brown discharge. Now when I wipe, I spot brown on my toilet paper. I had no PMS symptoms... Am I pregnant? Before my period was due I took 3 pregnancy tests. All were negative. But I'm still scared I maybe pregnant...
