My partner and I have been trying to conceive for about 6 months now. During this time I have had 3 separate positive pregnancy tests and they have all been fallowed but heavy bleeding 3-7 days later.. is this chemical pregnancy? Should I try to go and see my doctor after this happens? I can’t help but think there’s something wrong. I didn’t experience this when I had my son. Are chemical pregnancy different than a miscarriage.
