Thank you so much for this service! I have been skipping my periods with continuous birth control for several months. Sometimes I get some light staining so I always wear black underwear etc. This past Monday, I got the coronavirus vaccine booster (shot 3) as I work in a hospital setting. On Wednesday, I got some staining but it was heavier than usual. I made sure to continue to be careful to wear black underwear, not look at toilet paper etc., but the staining has been going on for a few days, accompanied by cramping. I am worried that it will get worse. If it turns into a flow (which I am unsure of how to gauge), when would I start counting the five day minimum? Thank you again!
