My period is 3 days late, no sign of it coming. Even though I know I ovulated on time (possibly sooner) I’m having ovulation like discharge and have been for 4 days. I’m having none of my usual pre pms symptoms but I’ve noticed a few new things that could be pms or pregnancy. I took a three tests this AM and all were negative, should I be worried?? I had some slight discharge/spotting stuff on the 10th towards mid day (not typical post sex blood) it was white/brown tinted and thick And lasted maybe 2 hours.
