Can she still be pregnant if...?

absolutley. all home pregnancy tests are not 100 percent accurate. If the tests you give her are negative then retest about a week later or take her to get a free pregnancy test at the clinic.

some pregnancy test come out negative because you are early on in your pregnancy. thats why the pregnancy test instructions are to take the test first thing in the morning when your HCG level is the strongest ( HCG is the pregnancy hormone, and its strongest in the morning cause you went all night without peeing)

If she takes it late in the day her HCG hormone might have not been strong enough to show up on a test and make is produce a positive reading result

Yes, of course. If the test was saying pregnant theres no way it could be wrong but a test saying not pregnant theres every chance it could be wrong..

Although she could just be thinking into it to much. I would still go to the clinic just incase.

Yes, she can still be pregnant, when I took a pregnancy test one week, it was negative, and then the next week I took a test and it was positive, and the level of HCG was detectable by then.

I would still take her to the doctor, and/or Planned Parenthood, to help her out.

Its very rare but still a possibility. She needs to book in with her GP and have a blood test as this will tell her once and for all xx

yes, but most test are 99% accurate best thing to do is go to the doctor to know for sure
