I agree with the other posters. No one can tell you if she is pregnant. Chances are she isn't due to the negative home pregnancy tests. Many things can cause a late or missed period...and pregnancy is only one of them.
If your gf does not want to see a doctor, wait a week and if she haven't gotten her period, retest. If it is still negative, she may want to see her health care provider. Use the first urine of the day (first morning urine) for best results
Well if ur having unprotected sex then there's a possibility or if she's worrying or stressed out about something then that's another reason for lateness, but the only way to tell 4 sure is to go to the doc and get blood drawn. Goodluck and if ur not trying to get pregnant use protection.
No 1 can tell you she's pregnant . But my advice to you is if she hasn't had her period ask her to take a test in the morning with the first morning urine and see what the results say. If it still says no and she still hasn't qotten her period then I would suggest getting a blood test done to see if she pregnant or not. Symtoms font really mean anythinq and the symtoms can also be for a lot of other reasons
