I was 7 weeks and 3 days pregnant but it end up in a miscarriage, i started bleeding on d 22 feb to 4 march. On d 2 i was just spotting so me n DH had sex. Went for my last scan on d 6 of march they said there was no need for D&C coz my body has clean everything out and they did HPt and it negative. Now have started having symptoms again. My boob are getting big, feeling sleepy all d time. I want to test but i dont know if is still early.
