Miscarriage in 2014, no luck concieving

Miscarriage in 2014, no luck concieving. in October 2015 started bleeding and didn't stop until my doctor tested my insulin levels and we found out I was insulin resistant. started metformin 12/15/15 and stopped bleeding finally since October on 12/20. Had a D and C on 12/23. found out today I am 4 weeks pregnant!!!! We go for ultrasound in 2 weeks. praying this is a viable pregnancy. Freaking our a little because of the lining of my uterus being thinned less than a month ago. weird I was already on my way to pregnancy before d and c. Keeping the faith and leaving it in God's hands. So happy!!!
