I'm afraid I agree with Squad. It is quite common to miscarry at about 6 weeks especially if it is a first pregnancy (about 1 in 3 I believe) and for it to be like a heavy period. Before there was home testing for pregnancy and being able to find out you are pregnant almost straight away, more people are getting disappointed when they miscarry at this stage, years ago you would have just thought you had a late heavy period.
It would be nice if Sqad and I were both wrong and I hope we are.
Best wishes.
