Yes. It tends to happen. I had two prior miscarriages before having my third pregnancy. My first miscarriage was when I was four months pregnant and then followed by my second miscarriage which is two years later. When I was pregnant for the third time, I was so afraid of having another miscarriage. I had threatened miscarriage during my third pregnancy and was on complete bed rest during my first trimester and took progesterone injections every 3 days for the first trimester. But right now, my baby is turning 10 months old and I felt everything was worth it. I am sure you will feel the same way too, don't be discouraged about it.
