Septate Uterus surgery. Confirmation.

Hi, We were planning for a baby in Sept. 2015, but it didn't go well, fetus didn't grow well and ended up with miscarriage in 10 weeks. Doctor informed that this could be because of partial septate in uterus. Performed surgery in Dec. 2015. After that i was having regular periods but reduced flow and shorter duration. We are regularly trying since Apr. 2016 to conceive but no luck. I am on FOL123 5mg medication since Mar. 2016 Last month, my periods were after 35 days, this month again after 35 days it started for a day and stopped. I stopped medication and periods started again after 5 days and are continuing since past 10 days with normal flow. Now i am suffering from heavy gastric issues, vomiting, loss of appetite and sudden mood swing. Kindly help. . Also advise if it is ok to take FOL123 5MG for such long duration, or should be started aftrr pregnancy confirmation.
