Since you have been trying for the past nine months without any positive result, I suggest that you go for further management at the hands of an expert. Your sonogram suggests polycystic ovaries
, if you have not been induced. The follicles in the left ovary are mature enough to rupture and this is the time to follow regular intercourse, at least on alternate days. Monitoring ovulation can be done by sonogram, basal body temperature
recording and cervical mucus test. Doxycycline should not be used while planning to conceive. Hope this helps.
