Our third miscarriage

My husband and I found out that we was pregnant on April 1, 2015 (No April Fools). I made it passed the 6 weeks and 5 days and doing well. I've had two other miscarriages in two years in a row. One in 2012 and 2013. We made it to 15 weeks and 5 days. On Sunday June 14, 2015, I started to experience some cramps and discomfort. They were coming and going throughout the day and didn't think much. Because a women's body goes through so much changes and feelings. Well, that evening aftet dinner, I felt a pop and had clear liquid come out when I used the bathroom. I called UK Triage (University of Kentucky) and explained and they said to come in. I told my husband that we have to go to the hospital now. As we were driving there the pain got intense and so did the blood. Finally got there, and as I was undressing and about to lay down on the bed, I felt the baby coming out. Our baby wasn't doing anything!!!! It's been two weeks since out loss and we've or mostly me have been having a difficult time with my emotions. That was the farthest that we have made it. We was supposed to go for an ultrasound on the 15th of June to check on baby and my cervix. My ob high risk is worried about the size of my uterus, the strength of my cervix, also of how much radiation I did have when I was 6.5 yrs old, and finally they are curious on why it's taking us so long to get pregnant. We will be trying one more time and hoping for the best.
