I am 9 years post tubal ligation. I have had 3 c-sections and 1 miscarriage. I am 17 weeks late for my period. My uterus is distended. I recently started feeling fetal type movements. I thought it could be gas but then I was having gas and fetal type movements at the same time. I am very sleepy, sore nipples, and extreme heartburn. Over the last 4 months have experienced nausea, lightheadedness and vomiting. I am not very regular with my periods never have been but never had any trouble conceiving that's why I had a tubal ligation. I took 2 pregnancy tests at 14 weeks which were negative. My last pregnancy I didn't get a positive pregnancy test until my 5th month and felt the baby moving inside me. Should I be concerned or am I just imagining things? I am not yearning to be a mother again but I rather be pregnant than to have something seriously wrong with me? Am I pregnant after tubal ligation or is this signs of a pregnancy?
