Round ligament pain or lightning crotch?

Damaris

Hello ladies I am 21 weeks pregnant and I'm on my second pregnancy. I lost my first baby at 21 weeks just this February. This time I got the cerclage at 18 weeks but I'm not gonna lie being on the same week mark as when I lost my first baby is giving me so much anxiety and everything that hurts makes me panic. So I've been experiencing some sudden sharp pains that start off down in my crotch but I feel them on my right side of the lower abdomen. I also feel sore down there like I got punched. Any idea what it could be and how to relieve it?
