I had a hcg trigger shot done saturday confirmed positive opk sunday prior to <a href="https://glowing.com/glow-fertility-program">IUI</a>. Just took another opk tonight 3 days later and line still dark. Am i still surging or is it from the trigger shot? Should i continue bd? Im exhausted and dont really want to lol. Has anyone had this experience after a trigger shot. Normally after i get positive it returns to no line about 2 days later.
