I went through similar problems with my second pregnancy. i was also 35 then. So maybe my experience will give you some hope.

The most important thing is to find a GREAT infertility doctor in your area, although most OBGYNs do perform infertility exams. The real infertility doctors are reproductive endocrinologists.

One more thing: my doctor told me that in many cases, even though the ovulation test (using the kit) is positive, it does not mean that you actually ovulated. It's possible that your body is ready to release the egg (that's why you get a positive reading), but the egg is never released for some reason.

What he did to me is that the first 3 months, he put me on ovulation induction drug (Femera). On day 3 of my period, I go to the office and get an ultrasound to make there is no cyst. Then from day 3 to day 8, I take Femera for 5 days. On day 11 (or day 12), I get another ultrasound to see whether there are follicles forming. If there is mature follicle (eggs are forming), then on day 13, I will inject myself with one shot of hormone to induce the egg. Egg will be released within 40 hours. Then I do the work with my husband. On day 21, I go to the office to get blood work to check whether I have ovulated or not by checking  Progesterone level.

I was not successful after 3 cycles like this. During the last month, I finally did the HSG test and my tubes are both open. My husband is normal too.  The doctor's conclusion is that my egg may not be active enough. In the next two cycles, starting from day 3, I was doing hormone injection (I forgot the name) everyday (75 ul each) for 5 days, in addition to Femera. On day 12, i saw 2 big mature follicles. Then I did another injection that night to induce the release of the egg.

I finally got pregnant during the second month.

My other point is maybe the natural IUI is not working because your egg is not active enough. Before this infertility doctor, my regular OB told me he would do IUI for me immediately. I am glad that i didn't waste my time with him. I believe that the hormone injection really made a big difference.

I was getting very desperate too, and the doctor told me that if I failed again, he would have to do IUI or IVF on me. But I am lucky this time.

Hopefully, you will be lucky too. Good luck!
