I'm at work and I realized my upper abs are really hurting like I did 50 crunches or sit ups. I've only slept today and worked. Monday I had my first <a href="https://glowing.com/glow-fertility-program">IUI</a> so I'm wondering if its an early sign of pregnancy, or I'm just hoping to much. I have a progesterone test on Friday but this is bothering me. Any one have this problem with early pregnancy?
