Hi, I Underwent An Ivf Cycle This Month Followed By

Hi,
I underwent an ivf cycle this month followed by Freeze-all protocol. I was put on Meprate day after my OPU for 7 days. I happen to miss my last 2 doses of meprate. And just after 2 days of that,I started to spot. I'm not sure if this is how it should be...and if I should take another dose of it anymore. Please advice
