I have pcos. Periods were irregular.had an ectopic pregnancy after treatment on clomephene 50mg followed by follicular study.01 tube was removed. On try since 01-02yrs not getting pregnant. Left over tube was patent on dye test. Taking metformin 500mg since 1 year. Lost about 10kg. Periods now came to the track. But not getting pregnant. Am I not ovulating? Husband count is normal. Will I be able to conceive normally or should I go for ivf?
