Hi, My cousin, 23 year old is on her period right now. Her concern is that her flow is lighter than the usual. She uses she cup which generally gets full in 9-10 hrs on the 2nd day. But this time it was half full. 1st day of period, the flow was usual. She is worried if she might be pregnant as she had intercourse, with protection (condom) which did not break, but thinking randomly about all possibilities, something might have gone wrong there. She is having usual period cramps and back pain as well. Other than this there are no symptoms at all. She is a bit stressed due to family problems. Please help with your insights on the same at your earliest.
