Period?

Crystal • Three kids!
Hi all. I'm new to post. I am so confused with my body because I'm always normal with regards to my period. It's a 25-26 day cycle. Ever since my miscarriage last year and my d&C, I don't know why it's taking me a year now to TTC. I finally got a second opinion with a fertility Dr and he did an X-ray with some liquid to see if my tubes are clear. The Dr said that if they're blocked then this would clear it. It's time for my period and I had spotting on day 27! Now I'm on day 28 and no sign of period. I don't know what's going on. I don't want to get my hopes up and test because I've been disappointed for twelve cycles already. I want to know if I am going to have it because I plan on having my third <a href="https://glowing.com/glow-fertility-program">IUI</a> this coming month but this will be a SO-<a href="https://glowing.com/glow-fertility-program">IUI</a> so I need to take meds on Day two of my period. I'm so confused. Last night I had years because I saw spotting.
