I've been having unprotected sex and missed at least 11 pills or more this month. My nipples were sore from 1/12-1/17 and on the 17th I took a pregnancy test but it was negative. On the 23rd I had a light brown/sometimes pink discharge when I wiped that happened for about 4 days (stopped on 27th). I've been on the pill Microgestrin for 6 years and use the pack continously and don't get periods. I've been peeing more frequently and I sometimes feel sick in the mornings before I eat. Should I take another pregnancy test? Did I ovulated? Please help....
