My finance and I had protected sex around the time of ovulation (have been using condoms for nearly 2years and the pill for 7 years prior to that with no scares). Condom was used correctly (we are not planning a pregnancy). I have had some red blood spots in clear discharge about 2 weeks ago (sorry TMI) but no period. I have had period type cramps but no af. I took a test 5 days ago just incase which was negative but I'm now 2 days late. When would be a good time take another test is my period doesn't show up?
