Sir, I have regular periods from past 9 years though my cycle is of 20 to 25 days. I got my periods last month on June 2 and expected my next periods today that is 27th June since I always get my periods 5 days before the last month date. I didn t get it still. I m worried because in the 2nd week of May I had a little intimate time with my bf. But we didn t have sex. It was just a little touching and all and I did get my periods after that on 2nd June. But I read online that we can be pregnant and still have periods. I m very very worried. Please help. 2-3 weeks back just for a few hours I had pain in my lower back. Other than that there are no symptoms.
