Placenta Previa

Michelle
Anyone else dealing with placenta previa? 
I'm 24 weeks pregnant, from our third round of <a href="https://glowing.com/glow-fertility-program">IVF</a>. Apparently, the likelihood of previa goes up with <a href="https://glowing.com/glow-fertility-program">IVF</a>, particularly if there's any prior scarring of the uterus (which I have, from having the fibroid scraped out pre-<a href="https://glowing.com/glow-fertility-program">IVF</a>).
They say the second trimester is the golden one, when I should enjoy being pregnant. I'm just so scared all the time. I check for blood every time I go to the bathroom, wondering if this will be the day all hell breaks loose.
Anyway, I could really use some support here. Thanks.
