my friends boyfriend came in her twice, she's 15 years old. She said her period was like 5 days late but she normal gets her period for 7 to 9 days this time it was only 3 days started light then was heavy for about 3 hours then went light again. She's taken home pregnancy test but they come back negative. Her mom had that same problem with her 4 pregnancys she was getting negative hp test and went to the doctors and she was 8 weeks. Could that happen to her too? He stomach is getting a little bump , she's eating sooo mcuh, randomly she will feel like she's going to throw up, she get headaches, backaches, he boobs are getting bigger, her friends are even asking if she's pregnant because they can see a bump. Does planned parenthood do blood test? Or would it have to be your normal doctor?
cramping A lot.

Is this a "Friend" or is it really you?

Adult games have adult consequences... so she... or you need to face them like an adult.

If she were pregnant it would be too early for a "bump." She/you will have to wait until your next period is 2 weeks late then test using first morning urine.

At a few days late, there is no "bump" or really other signs, sounds like imagination or worry seeing things. You can not test this early, you have to be at least 2 week late, and test with first urine of the morning. Yes some women will not test till even 2nd month but this is rare.

Wait and do test after 2 week

Way too early for a bump. The majority of women don't get a noticeable bump until their second trimester (second trimester is 4th, 5th, and 6th month), of pregnancy.

No one can diagnose pregnancy online. Could she be? Heck yes! She's sexually active, and she's not using protection. Even with protection, pregnancy is possible. She's trying to conceive, she's having unprotected sex. Obviously she wants a baby, even if it's a horrible idea at her age.

She'll have to do what every other woman on the face of this Earth does. Wait, test, and see. She needs to wait until her period is at least 2 weeks late, then test using first morning urine. If that test is negative, wait for the next period, and if it's missed, test again or get a blood test done.

If she wants to be responsible enough to have sex, she has to be responsible enough to be a mother. At 15, there's no way she can support a baby on her own, and she will be on her own. Teen boys don't stick around around after they knock you up. They wanted to get their dinky stinky, nothing else. They won't be there when baby is screaming at 2 in the morning, and the court costs to get them to pay $40 of support a month, will be out of your reach. Sorry, I mean your "friends" reach.

The best advice she/you can receive, if she/you dodges the bullet this time, is to keep her/your legs crossed, shoo away all penises that want to play with your/her vagina, and wait until she/you is ready for a baby. Ideally that would be when she/you has a college degree, a career, and a husband.
