I am "regular" too but Clomid just ups the chances. Per my doc, it tricks your body into thinking you are menopausal and the body fights back by dumping more eggs in an effort to conceive. Good luck.
I am also in a similar situation. Mid cycle ultrasounds have shown that I am definitely ovulating on my own - always out of the right side, but that my uterine lining was on the thin side. My RE wanted me to try Clomid with the intention of having me release more than one egg to increase the likelihood of fertilization, even if it sometimes does thin the uterine lining even more. I took Clomid for one month but did not have any luck, but it did appear that i had two eggs about to be released instead of the usual 1.
The RE finally convinced me to have a laparoscopy and it turns out that I had adhesions that were not showing up on any of the tests that had been done. My right ovary was covered and attached to the wall of my abdomen, so no eggs would have been able to make it to my tube (on that side anyways). I had previously had a HSG in April and that came out AOK.
Not sure if my RE will want me to try Clomid again next cycle in an attempt to increase the number of eggs released or if he will want us to try on our own now that my ovary has been uncovered and unattached. Even though DH's initial SA came back OK, I'm thinking it wouldnt hurt to investigate him further too. Who knows - my follow up appointment with the RE will be September 8th, so maybe I will get some more answers then.
But in regards to your question - I think that prescribing Clomid is normal procedure, even for women who ovulate on their own but have unexplained infertility. I do have a friend, who at age 37 got pregnant on her first round of Clomid even though she knew that she O'd on her own.
Best of Luck,

I am in a somewhat similar situation. All of my tests have come back good and DH only has a slight morphology problem, so we were officially diagnosed "unexplained". My OB/GYN put me on Clomid for a few months. The theory being is that it creates more eggs and more eggs mean more targets for the swimmers.
I didn't have any problems with the Clomid, but now I am seeing an RE and she is going to put me on Femara. Eventually we will be doing an IUI.
