I still had a period last month in march but it was very shot which is not normal for me and it was about 4 days late I have been very tired, nausa, smells of things make me sick and I have an odd feeling in my stomach. I took 3 urine at home tests and they both came up negative could I bee pregnant. If not there is something wrong with me because I have felt like this for about 1 1/2 months.
