So Ready to Give Up! Ugh

I'm so ready to give up. We've been TTC for 5 months since my last MC ever month negative. Plus I started my cycle 3 days early. I'm on Femara to help me ovulate and add preseed. We have sex all the time what are we doing wrong. I'm going to be 34 in a few months having gone through 3 MC and 1 stillborn every one around me is getting pregnant when is it going to be my turn to have my rainbow baby. So for the rant just feeling really down and useless. Trying to stay positive and making dr appt soon to see about a different treatment. Praying for all for lots of baby dust one day it will be all our turn
