 [ Symptoms ] could i be pregnant i have been nausea can not keep anything down i had a tubrilligation 16yrs and birthconrol mesh 2trs ago my abdomen is getting hard and my belly is getting a little bigger and i am getting constant headaches and can not stand the smell of a lot of stuff it makes me sick i remember feeling like this when i was pregnant with my other kids [ Disease ] i would wonder about a false pregnancy sometimes the body can produce pregnancy symptoms when you are having a hormonal imbalance the reason why i think that is because tubal ligation is pretty sure and the essure mesh has a 99 8 effectiveness when properly implanted so pregnancy would seem pretty unlikely better check with your doctor
