Just had second ectopic pregnancy and my only chance now is ivf. Wt is the process like, I am in Africa and looking for a sponsor as we cannot afford it?

You really need to d. Discuss that with the doc who recommended it as it involves a lot of meds and a procedure to harvest your eggs and then fertilize with your husband's sperm and put back inside your uterus bypassing the tube.
Ectopic pregnancy. I think you need a comprehensive evaluation to figure out why you've had ectopic pregnancies before you commit to ivf. It may be that you still have a chance. As far as having a sponsor, that's challenging as it doesn't appear to be a life threatening condition and not too many charities would be willing to sponsor it.
