Okay so my periods are irregular they come in the beginning of the mom or the end I never know when it's will come but I've been bloating, having cramps, boobs are sore nippers hurt when anything touches them, I am constipated and then next day I got diarrhea, nausea, tired all the time.. I took two test they both said negative but I think I should get a first response test I think it'll be better... cuz I don't want a false negative and this would be my first time...
