[WoodyA]

Ok, so I had a mc in march
AF April 17th 35 day cycle

Dtd from cd6 until cd34 every other day

AF came cd34 night very light blood stained cm
Cd1 very light blood stained cm
Cd2 normal bleed
Cd3 very light scanty bleeding
Cd4 brown spotting
Cd5 (today) nothing

My AF are usually VERY heavy clotty and very painful last 6/7 days and at least 2days very heavy bleeding

I've had on and off nausea and constant tiredness
I tested cd3 and got BFP using IC but bfn using frer

I've had false positives on IC before

Anyone experienced anything like this?

Thanks!!!
