2nd iui...15 dpiui, help!

Jessica

This is our 2nd <a href="https://glowing.com/glow-fertility-program">IUI</a>. We got pregnant on our first round, but sadly lost it 2 days shy of 10 weeks. 😔 That was 4 months ago, this is our first round back. Medicated with trigger shot. Today is 15 dpiui. Yesterday was my test day, bfn. Today, another bfn. Period is now a day late. I had pretty intense cramps much of the day Friday and was sure my period was coming right on time Saturday. Today the cramps are gone, but I now have sporadic sharp or twinge or grabbing like pain on my right side. It's not consistent, but every 15 min or so. Anyone get a bfp this late!? I'm thinking I'll call tomorrow if my period still doesn't show and I'm still getting negatives. 🙄🤞🤞
