In November while having sex my husband wore a condom wrong and realised it immediatly and corrected it. I am scared i might be pregnant because any precum that might have been on the condom. i have irregular periods. in december my periods was delayed by two weeks but when it started it was very light and lasted 5 days but i got a normal and heavy period in 1st week of January which lasted for 5 days. but in Feb my period was heavy on 1st and 5th day and light on the other days. I have taken a number of home pregnancy tests and 1 blood test and all have come negative. But i have gained weight and i am experiencing little breast soreness and a pull in my lower stomach from past two days. I have not had sex after november. Could i be pregnant by any chance or I am just imagining stuff due to stress?
