i used to drive my doctor nuts thinking i was pregnant all the time and the worst part was the stress i was causing myself was affecting my periods so they would be late making me think i was pregnant even more it got to the point where i would finally get tested it would come back negative and my period would start within a few hours it was weird this was back when you couldnt buy tests at the dollar store and i couldnt afford them at the pharmacy so there was no way for me to check without my doctor being involved tgat poor doctor man she was a champ for sure
