recently I'm having a problem with my menstrual cycle. I've never had late peridos and they usually come in the days 24 to 26 of the cycle. Today I'm already 1 week late and I'm having cramps and pain in the low back side like I usually have before my periods come. I've had these symptoms for more than a week now but all I got is today a blod clot. As I'm sexually active I've also done pregnancy tests which all resulted negative (the one with blood as well). I had a visit to the doctor and he noticed a cyst and said that periods may be late because of hormone changes and he gave my pills to use for ten days and then my periods will come, but I didn't take them.
I would really appreciate your answer,
