I might be pregnant? I did have unprotected sex and had my period a day late. My period is not like my normal cycles.. It came a day late and at first very light then heavy for one day and now light again. There is no clotting but I do have cramps and I am feeling a little bloated. Its been three days only and I feel like my period is starting to end -my periods last 7days. Right now I am feeling extremely exhausted and quite dizzy also a bit nauseas but I'm not sure if I'm just thinking too much? I did test because I was a day late and the test came negative. My boyfriend assumes I could be pregnant.
