My husband and I had our son on this past Christmas Eve 2012 and we use condoms every time that have not ever broken . Also I'm on birth control I always take it on Time and never miss. I am constantly feeling cramping that's just notisable and have a good bit of discharge and this past period I was four days late and had a much lighter period and my stomach has been so upset and I've been nautious and last night I vomited . Is this normal? Or could I be pregnant ? Even though I don't see how I could be with all the precations we are taking.
