Bcp breakthrough bleeding? Ivf

Nia

So I’m on my second to last active pill before starting my <a href="https://glowing.com/glow-fertility-program">ivf</a> cycle and my period seems to be starting. I was spotting very slightly the entire time I was on the pill but now it’s starting to come in heavier. My clinic is closed for the weekend but I’m worried that the pill isn’t working the way it should before an <a href="https://glowing.com/glow-fertility-program">ivf</a> cycle. Has anyone experienced this? I’ve done 2 other <a href="https://glowing.com/glow-fertility-program">ivf</a> cycles and bad zero problems with the pill, the only difference this time is that I’ve been exercising and eating pretty healthy. Help! Thanks!
