Me and my wife are trying to conceive for 2 years. She started having irregular periods 6 months after marriage. Doctor did laparoscopy, tubal test and ovarian drilling for pcos. She is having induced periods after that. After inducing periods, doctor directly started giving FSH injections 75 mg and follicular study. He concluded that she is not ovulating and decided to double the dosage next cycle. But she ovulated late that same cycle and got pregnant. But it ended up in a miscarriage after 6 weeks (spontaneous miscarriage). After one month doctor again started giving FSH injections and she started having heavy mid cycle bleeding. She consulted another doctor and she gave her metformin 500 for 30 days and siphene 50 mg without follicular study. That month she got her periods naturally. Right now she is only taking metformin. Will this help her to ovulate naturally. She got periods last months naturally. Does that mean that she ovulated last month? Her tubal test is clear and hormonal profile is normal and no thyroid issues. Her weight is 72 and height is 5 feet 4 inches.
