Geritol + late Period

Priya
Hi everyone,
I started Geritol tonic on 10 day of my cycle. I have 28 day cycle and I am 4 day over my supposed period cycle. Did anyone experienced irregular or delayed period when they 1st started Geritol? I am not experiencing any pregnancy symptoms. Except that I had pink color discharge with Mucus for 2 days only when I wiped (so not standard spotting) this was 4 days before my cycle. Just curious. I am TTC and had few failed <a href="https://glowing.com/glow-fertility-program">IVF</a> and Doctor said since due to low AMH I might not get pregnant. Don't want to take test for another few day. So any info or if anyone experience same thing please let me know.
Thanks!!!
