So I had a miscarriage on March 29 and af hsnt made her way around yet ! I've had sex with my hubby but he pull out all the times we did it . Today all day long I've experience a very light blood spot VERY LIGHT THOUGH. Not bright at all. No tender boobs or anything. Took a test and it was beg so levels are down to 0. What could this be what hasn't af showed yet ?
