I had my period until Wednesday or Thursday last week, it had lasted 5-ish days as usual. Today I started bleeding again though. I have no idea why this is happening; I've always had a regular cycle and I don't take the pill or anything hormone-related. The current bleeding doesn't seem to be very strong, and I do feel similar to my usual "first day period pain", but it's less intense than usual. Should I be worried? Couldn't go to the doctor now before Monday anyway...
