I have not had a period since May 28 and which it lasted about 4-5 days long. I had sex with my boyfriend on June 16 without protection. I didn't have a period for June nor have I had one for the month of July yet. I took two test and they where both negative. I am starting to have hurtnurn as of tonight. I could not sleep last night for some old reason which is not usual for me. I feel like I can feel two heartbeats in my throat. Breast tenderness, feeling sick and certain smells make me feel sick and emtional sometimes. Could I be pregnant?
