cramping and a nervous wreck

Ashton
I'm high risk due to PCOS and a previous miscarriage at 4 weeks. I am now 4 weeks again following an <a href="https://glowing.com/glow-fertility-program">IUI</a>. I'm having some mild cramping almost like a stretching feeling. Is this normal or should I be worried.
I'm so worried about another miscarriage.
