I recently took 2 pregnancy tests & both had positive results, so calculationg from the first day of my last period I should be about 5 weeks pregnant, but I started cramping yesterday and bleeding last night - could this be a period and I have miscalculated or could if possibly be a miscarriage?

Sounds like your having a misscarrage go to hospital asap hun I have had 3 in 5 yrs

Since this post was back in May, I am pretty sure she knows by now whether it was a miscarriage.
