Pcos,HPV,endometriosis, 3 miscarriages and 1 chemical pregnancy

I have previously been able to produce a BFP but they have always resulted in miscarriages or a chemical pregnancy. I have been with DH for 3 years and just started taking the initiative of really trying to concept our hopefully first child. I recently discovered ovulation tests and began taking them. I have come to realize on my very first cycle of tracking for my LH surge that it may by happening a lot later then I expected..any similar story's or advice on this would be a amazing..I'm trying to be positive but wanting something I may never be able to produce has discouraged my heart,but I'm staying positive ..any ladies out there that can bring my hopes up or storys of a similar experience would be very much appreciated...
