How can you tell if its implantation bleeding? I'm on CD 18. Just got off my period exactly 2 weeks ago. It was my first cycle since my miscarriage in December. Hubby and I have been BD every other day since I got off my period. I've been testing ovulation for about a week now and it hasnt come up that I've even ovulated yet... but is there a possibility that I could've ovulated right after my period and not known? I never in my life have had a light period like this or any breakthrough bleeding or spotting. Its NOT normal for me to have light bleeding mid cycle. Please help!
