Hi, I just have a question, last month when I had my menstrual cycle, it was about a week later than normal and when I did get it, it was lighter and shorter, like I only had to use maybe 2 super tampons the entire day, and it only lasted 4 days, when my usual lasts between 7 and 9 days. I have been having unprotected sex for 3 months now and I know the possiblity of pregnancy is there I just don't know how high. I have felt a bit queasy the last few days and have not been as hungry as usual. No other symptoms though. So I was just wondering if I could be pregnant and have been last month and just not have know it. Thank you.
