Hi, I had lap and they burned away as much endo as they could. Then had mirena coil fitted for 5 months until I could not bear it. My consultant then prescribed 6 months of prostrap as we wanted to try for baby and he said the prostrap would reset my system and give us the best chance. I managed to last the 6 months on prostrap and we tried for about 12 months with no luck. We finally decided the stress was too much and we would give ourselves a break. I found out I was pregnant 3 weeks later. I think stress plays a huge part. However I definitely think the surgery and prostrap combo worked for me as we had been unprotected for a good year before and nothing.
