Is Laparoscopy Recommended To Diagnose Infertility Problem?

I m 29 yrs old , weighing 57 Kg .I am suffering from PCOD and under medication since last august.I was prescribed Ovacet twice a day and since nov 14 my periods have been regular and ovulation has been proper. I have had TVS Scans almost every month and accordingly having unprotected intercourse on dates (as per Scan results)when follicle ruptures which mostly comes by Day 14 .My tube test is normal , husband semen test is normal. Even antisperm sntibodies test for both my husband and me is normal and within limits.I m regularly taking ovacet .my gynae says everything is normal and it is matter of chance only .with Gods grac, I shall conceive. She says no more tests are required. It is unexplained infertility .On last vist , she recommended laproscopy of abdomen to further analyse infertility.Pls advise , if laproscopy would helo in any way ? also advise if any other test/ medication is required.
