I am freaking out!!! I am 37, I had 3 c-sections and three years ago after my daughter was born I had my tubes tied. My first born died of SIDS and we thought after I had a boy and a girl, we were done but, last week I started having many symptoms that I think I may be pregnant. Is this possible? I did take an at home pregnancy test, but it is negative, but I think it may be to early. My period is not due for another 10 days. Am I freaking out over nothing? Help??
