Period during IVF

Hi I’ve just started <a href="https://glowing.com/glow-fertility-program">IVF</a> and I’m on day 3 of my cycle and my period is pretty much finished.. does anyone know if this is an issue? My periods are generally 3-4 days including light spotting at the end but I feel like it’s ended a day earlier this time and I hope it’s not an issue
