Hi I need some help. I completed a invitro in July, and everything was going well, In August I spotted a little,and then I passed a tissue about two days later I had cramps, and vomiting for couple hours. My period continued for five more days then it ended. In September I did not receive a normal period. I only spotted and had brownish discharge nothing heavy. Can someone please tell me what this could be, can it be that I had a miscarriage but they could have still been another child still in my womb.
