PREGNANT AFTER MISCARRIAGE!!

I got told by the hospital in January 2016 I couldn't conceive children and would need to have <a href="https://glowing.com/glow-fertility-program">ivf</a>. Found out 1st may 2017 I was pregnant miscarried on the 4th may 2017 it has been 8 weeks and today 5.7.17 I have found out am pregnant again. Kind of scared incase it happens again. Anyone been through similar situation?
