Ectopic pregnancies r not viable as the embryo has implanted itself in ur tubes instead of ur uterus. I'm sorry to say, but I wouldn't wait it out if the embryo is growing then ur tubes can rupture and cause massive bleeding which is not good. If it were me I would get confirmation via ultrasound and if it is, then terminate the pregnancy asap.
If it's grown and not in your fallopian tubes,have faith momma. My little one had a slow heartbeat as well in the beginning. Now I am seven months along with a healthy baby. Good thoughts and prayers for you.
Thank you Mary this is very reassuring. The pregnancy is in the womb. Going back for another scan in 10 days. Keeping everything crossed for good news. We've been trying for over 2 years. Thanks for you advice xx
