So, my girlfriend is 19 and not on the pill. She had spotting 2 weeks before her period and it lasted 9 days. Once we got close to her period about to start we took a HPT and it said negative. Sofar she is like 10 days late of her period but she says she feels it coming on. Im sure this is irregularity or something. Any advice?

If you have had unprotected sex there is always a chance of pregnancy.

It may have been too early for the test to pick up any hormones levels.

Many things can delay a period,illness,stress etc.

My advice is if she does not get her period when she is two weeks late,repeat the test,if still negative and no period go to the doctor,if positive go to the doctor.

Use protection if your having sex,even at that no contraception is 100% safe.

I did use protection. Every time. No breaks or anything. I also pulled out every time.

Condom goes on before sex,I'm sure you know that but just thought I would say it.

No one on line can say if your girlfriend is pregnant or not.

Even if you entered her for a few seconds before putting on a condom,she can still get pregnant.

The only thing you can do now is wait,or go see a doctor for a blood test,which is more sensitive in detecting pregnancy hormones early on.
