Hi! I’ve been trying for a baby and I had a positive opk on CD19 so that’s when I BD’ed. 9 days past ovulation I started spotting and now 4 days later I’m still spotting. (only once a day and it’s some watery brown blood) It doesn’t progress into my normal heavy period. I’ve never had this happen before. My luteal phase is usually 11 days and now it’s day 12. I have AF like cramps and all negative pregnancy tests. My stomach keeps churning and I had diarrhea yesterday, but no real period after 4 days of losing a few drops of brownish watery blood once a day. What could it be?
