So March 1 I spotted a bit. It was pinkish brown and very very light on toilet paper. I assumed my period was about to start because I also had some light cramps. I took a PT on 36 & 37 and both were negative. My last pregnancy ended as a missed miscarriage, however I found out I ovulated late then. When I found out I thought I was 8 weeks but was actually 5. So now I’m wondering if I ovulated late and that this spotting was actually implantation spotting. How long should I wait to test again?
