BFP but......!

YK

Hi lovely ladies, I have got my BFP this morning we are thrilled, but I have these cramps in my lower abdominal, feel heavy and some pulling. Is this normal, I had a miscarriage in July'2015. So I hope this one will stick around. TTC#1

And I wanted ro confirm that I should continue taking follic acid, perenatals & metformin, P. S - I have PCOS?
