Infertility/Miscarriage/Rainbow Baby Mamas

After trying to have a baby for almost 4 years, having 3 miscarriages, being diagnosed with PCOS, endometriosis, and having a tumor removed from my ovary, I am pregnant for the fourth time! 
I am excited and nervous at the same time. This pregnancy has made it longer than any of the last 3. All blood work looks good and I'm having good symptoms (sore boobs, fatigue, no bleeding, peeing all the time at night) but I am still scared because of our past history! 
We go in this afternoon for our first ultrasound to check on our little love.  When I put aside my fears, I have a good feeling about this one. Trying to ignore my irrational fears. 
Anyone else in the same boat of being pregnant after infertility or miscarriages? I need some mamas who get me! 😉
