negative tests can definitely be wrong...happens all the time. especially if you tested early. my first two tests were negative and now im almost 23 weeks!! so i would definitely retest in a few days once your late. if you ovulated later than you thought it can easily cause a negative result. also though premenstrual symptoms can be the same as pregnancy symptoms...or your mind can fool you into thinking your pregnant. you just never know! but i hope you are!! baby dust!! xxx
I am going thru just about the same thing over here, being that i ovulated jan 6 but had sex jan 4 and i was due for my period jan 20 and it has yet to come took 2 hpt's and they both were negative, it is now jan 25 and still no period but today i had lower back pains, but my suggestion to u will be to go to the doctor
