Ever since my <a href="https://glowing.com/glow-fertility-program">IUI</a>, I have had cramping every day. I don't think I am cramping from the <a href="https://glowing.com/glow-fertility-program">IUI</a> anymore but I'm unsure. I'm 5DPO and been having a dull cramp since day one. Could this be possible sign of pregnancy? I read that implantation occurs around 6-10 days, could this still be too soon to tell?
