TTC after Misscarraige

Megan • Deonté Jayden&Gabriel Jordon forever in my heart♡
I have had 2 second trimester misscarraiges. The first one was 11 years ago, I was 18-20 weeks, and the second was this past December at 15 weeks. I am 31 years old and I have irregular periods and have had my left fallopian tube removed so it's been hard TTC. I was on progesterone before this last pregnancy to regulate my cycle. I just started my firsr cycle after the misscarraige we want to try again but I am so nervous it will happen again. They have not been able to tell me why it's happened twice except that it not common to have 2 second trimester misscarraiges in a row. I have a plan and even switching to a specialist I just don't think I can go through that again. So trying to stay positive and hoping that it will happen soon!
