Hello. My husband and I are trying to conceive. Well we had unprotected sex in the beginning of October during my ovulation. About 4 days after I started get symptoms already. But my period was due Monday oct 26th and I started spotting on the 23rd into the 24th and then it stopped started again today which I think is from sex last night. But my normal period symptoms are cramping and sever boob pain 1-2 weeks before my period starts. I haven't gotten any of that. But I've taken pregnancy tests and negative. Do you think I could be pregnant?
