Im a very irregular woman and I always have a week late, or maybe more days late but lately I have been having my period with just a few days of delay maybe a week or so. This month Im being quite scared for Im already 11 days late and I already had acne breakouts, tender breasts and cramps. I always get dizzy in the morning until I have my breakfast so that's nothing to worry about. But still Im scared that I might be pregnant since I was intimate with my boyfriend on the 30th of may. He tells me that I'm stressed and that's why my period so late and also I made so much changes such as moving from the city to the rural zone and starting to walk and making excersises for I have gained too much weight these past 6 months. Is it possible for me being pregnant?

ANY time there is penile insertion there is the risk of pregnancy. The ONLY way to tell if you are pregnant is to take a test 1-2 weeks after you miss your period.
