I've seen a few people saying they've had a negative pee test but was still pregnant. I have been off of birth control for 3 months but was only on them for 3 weeks. I havent had a regular period in 2 months and none so far this month. My last period was a week and a half late and lasted for 2 weeks. But they are usually regular (5 days) I just took another test yesterday and its still negative. I'm not stressed or anything so I don't think thats why I havent had normal periods. But if im not pregnant what else is the problem? I have symptoms too. Sensitive breasts specially my nipples, headaches, fatigue, higher sense of smell and more. I know theres a lot of these but does anyone think I could be pregnant?
