Abdominal tightness

Hey ladies. I just underwent our 2nd <a href="https://glowing.com/glow-fertility-program">IUI</a> and I'm 5 days away from starting AF, I'm experiencing some tightness, "twinges" in my abdomen. My period cramps are always much lower than this and feel sharper. I'm not trying to get my hopes up, but wondering if this could be an early pg symptom. I googled it and there were a few midwives that confirmed RLP very early on as a symptom, especially if it would be your 2nd pregnancy (which this would be baby #2 for us.) Hoping for some of you to say I'm not crazy and it's a symptom. Lol. 🙏
