Talk to Gynecologist on Infertility

I had a n ectopic pregnancy which was abortrd using methotreXate on 10th june at 6 weeks of pregnancy. After that my beta dropped drastically and tvs was also clear which shows that ectopic dissolved completely. Before this preg i was on glucophage 500 mg. Now i want to ask whether i can start to take same dose of glucophage now to prepare myself for next conception? Or when can i start taking it again as i forgot to ask abt it from my gynae in last visit and she has given me the nxt appointmnt date after 3 months. ( my period started on 14 june and still is continued)
