After my <a href="https://glowing.com/glow-fertility-program">IUI</a> on Jan 14th I have been having cramps and a needlike pinching in my abdomen. Yesterday, I saw a very slight red blood only when I wiped with tissue, I was almost disappointed that my periods were about to start. But today, no bleeding so AF hasnt come yet. I woke up with a very heavy feeling but I was very busy at work yesterday so it could be due to work fatigue. When should I test? My period is due to come end of the month. I can’t wait, been TTC for almost three years.
