According to this app my fertile period started Monday (I haven't been taking any ovulation tests) on Thursday before I went to bed I had extremely light pink discharge which I usually only have before af starts a few wipes and it was gone. We had not had sex for about 24 hours so it couldn't of been rough sex. Now today (Sunday) I had the same thing except I noticed it after having sex. We didn't do anything crazy or that we normally don't do, lol. Could this be ovulation bleeding? I've never had it before. Af isn't due until 02/05 so I would assume way to early for implantation bleeding.
