Samantha
Hi I'm Samantha I just started metaformin and was on birth control for a few months to get my Psoc under control (which we did and now I'm off the pill yay) so I have no idea when my cycle will be but AF ended on 9-14. So have no idea. Ttc#1 this is our first time trying with the help of specialist. We have been trying for 7 years before this but with out good Insurance. I'm 29 and have been married for 6 and a half years. Um not sure what else have any questions please ask since I don't know what else to put and I have never done this before
