Clomid or Metformin? Opinions welcome!

LGM • 23. Wife. Fur Momma. Angel baby 11/1/17. TTC 🌈

Been off birthcontrol since July2016. Been TTC since. Conceived in mid Oct but lost baby @7wks on Nov. 1. Doc said to wait to get 1st period and have 1st cycle. Then to make appt to see what we can do and possibly start Metformin or Clomid (since we have been TTC for 1 1/2 yr now). Is Clomid more relaible than Metformin? Experiences pleaseeee and baby dust to y’all 💕
