So I had my last period on the 17th of January, when it began, it was a day late then. My last sexual encounter was being fingered on Christmas. So the period that
came was 3-5 days heavy and such. Its late again this month. Could that mean that it's trying to regulate to a new cycle length? Or should I go to a doctor and see

A period that comes a day after you expect it to is really not considered late yet at all. As long as a period shows up within a few days of the expected due date, it's perfectly fine. So, I do not see any cause for concern here.

Okay! Thank you so much!
