What is going on with my body? 😩

Jen
I had surgery in February to remove cysts and endometriosis. This month I didn't get a positive ovulation test until cycle day 20 and now six days later I am bleeding very heavily, I am assuming this is my period even though it wasn't supposed to start for another, estimated 8 days. My husband and I have been ttc for over a year and have used one round of femara and 2 trigger shots. Anyone else experience anything like this? It's not normal to start your period only 6 days after ovulation right?Â
