Ovulation study for conceiving.

I am 30 years old married 2.5 years before having regular periods on every 28/29 days of cycle. Trying to get conceive from last 1 year . visited gynaecologist before 7months she suggested to try naturally for 3 months more prescribed folic acid Tablet daily 1and suggested keep relationship mainly between 12th to 16th day of cycle. We followed it but not conceived so she had suggested to do a follicular study from day 11th,on day 14follicle size became 22 mm. She prescribed HUcog 5000IUI injection n did a sonography on day 16 in which it is found that follicle is not ruptured n it became a haemorrhagic cyst. Doctor told me to visit in next cycle. I visited her on day 2nd she prescribed Letsi2.5 for 5 days n tablet Ovabless Myo daily 1 n suggested to do follicular study from day 12th in this cycle size of follicle on day 15th is 22mm on same day I took hucog 10000 n did a sonography on 16 day but follicle is not ruptured n it became a cyst. Is it serious cause of infertility ?
