Pregnant after back to back losses

Madison

Hey girls, so my fiance left me may 26th, 2 weeks later I find out that I'm pregnant, we were trying again after our last loss in January of this year.. I'm excited about the pregnancy even though he left, but I am also very scared of losing another baby.. Anyone else have back to back losses and have a successful 3rd? They said 3rd times the charm, but since I'm alone now it's hard to stay positive.. Any advice?
