Prego after tubal??

Michelle
I have a friend who has had her tubes tied for over 3 yrs now but she's been feeling different lately. 2 weeks straight she's had nausea and vomiting and weird cravings. She also said her breasts were really sensitive and very sore! Her next expected menstrual is tomorrow but she's down and sad her period started a day early. She knows it's a very low chance of getting pregnant after a tubal but I have another friend who has gotten pregnant barely 3 yrs after her daughter was born. Anyone else on here ever gotten prego after having a tubal? She didn't think she wanted more children but that was way before her and her husband got together. Now they've been married for over a year and she wants to have at least one more child. She wants him to have a child of his own! Any help or advice for her will be gladly appreciated!
