I want to know every single possible sign of pregnancy because I feel my husband is having an affair with my bestfriend and that know she might be pregnant because she's been throwing up, having stomach pains, being really sleepy and drowsy,and has had a significant breast size increase (huge increase)and I know she couldn't be pregnant from her bf because I talked to him and he told me that they haven't had sex I'm months (2 to be specific)
