So advice❓❓❓While at the store, some complete stranger came up to me and asked if I was carrying twins... The last time I checked (bout a month ago) I'm not and I'm on birth control, I take a test once a month (right before I put in my new nuvaring) just to make sure my birth control is working.... Thats the first time anyone has asked anything like that since I had my daughter almost a year ago.. like I feel insulted and self conscious because of a complete stranger... What would you do????
