Bleeding from ovulation?

Last night hubby and I DTD and after when wiping I noticed a little pink on the paper. I put a pad on thinking I was starting my period but there was nothing more in the morning. I haven't had a period since the beginning of 2017 right before conceiving my son born Dec2017. I have pcos and haven't been worried about not starting cycles again but it has been 6m since stopped nursing. I took an ovulation tests this morning. Is this positive or could it have been positive yesterday? And that caused the little bleeding? We are not actively trying but not preventing either due to my pcos we just let things be.
