15/2! Clexane, Metformin, Asprin & Progesterone

I found out 3 days ago at 2w6d! Bloodtests confirmed that Im expecting after 2 miscarriages. 
Fertility Dr put me on Clexane injections, Asprin, Metformin & Progesterone after being diagnosed with PCOS & Hashimoto's. 
Anyone else with these conditions or taking Clexane injections?
