So I has a miscarriage February 12 and started ovulation testing soon after. I got a positive on march 8 and 9 and started my period march 10. Weird. Well, today I've been feeling really nauseated and but constipated (TMI sorry!). I've heard you can have a period if you conceive right before because it still takes 6 to 12 days for implantation. Am I crazy or could this be possible?!
