Fertility problem. Health but anaemic.

Hi, I m 28yrs old and expecting to get pregnant. I had visited a doctor 8 months back,she reviewed me and said I have PCOS and gave tablets for 2 months and after she did follicle study and said my eggs are not rupturing at the right time. She also reviewed my husband's sperm count and it was good. But medicine and injections didn't work. After few months I checked with other doctor and on the follicle study she said i don't have PCOS but my egg growth is poor. She also provided me many injections and tablets to have the egg grow. It also grown but I was not successful . Please advice what treatment should I take. Regarding my health ,my period cycle is around 35 days and gets period for 4-6 days and suffer a lot for the first 2 days on pain in lower stomach,legs and back. I have no thyroid, no obesity,no specific issues on health but anaemic.
