BW Please try not to beat yourself up hun. I was taking Metformin until my pregnancy was confirmed. I think from memory I stopped taking it the week after it was confirmed so hun that may not have made any difference to what has happened. I'm sorry that you are having a bad day but that is to be expected sweety. Remember its only early days atm and you will be feeling like you are all over the place. Your hormones and emotions are running wild atm and this may take weeks or even months to ease. Please take care of yourself. I think I had cramps and bleeding for about a week or so after my 1st m/c and about the same or maybe a little longer after my 2nd one so please try not to worry. Only if it gets very severe or heavy and a wierd odour then I'd start to worry.
