How Is Conception Possible Given Follicular Study Results With Irregular Periods?

Hi Doctor I am aged 34 years, my last menstrual cycle began on 1/2/14 lasted for 4 days which ended on 4/2/14, I had follicular study on 17/2/14. The report says no dominant follicle on right and left ovary, endo thickness is 6.5 mm and free fluid is nil. We are anxious to conceive since we had our last abortion on 21/2/13 by Rx, we also had TVS which says everything fine and no pieces anything as such. My period is irregular and 30-35 days. In December I had menstrual on 12/12/13. I had a bit big blood piece fell on 1/2/13 with much pain , once it fell off then I had free mentrual. Just before two days of that piece fall off, we had pregnency test positive. What is best suggestion of my situation to conceive?
