Am I pregnant or not, Is it a dodgy preg test?

I'm not an expert on pregnancy tests but it sounds as if you could be pregnant although it could have happened on another occasion. If you were having unprotected sex your boyfriend need not have ejaculated inside you for you to get pregnant as pre cum can contain sperm.
I'd suggest you make an appointment with your doctor to confirm one way or another

Go to the doctor. Go to a close family member and talk to them about it. Or go to your mom. My mom wasn't very supportive of me until I was 2 months pregnant. Your mom may be very supportive. Talk to your boyfriend. Just talk to someone. You could be pregnant and not even know.

Sounds like all the test you took were positive. It don't really matter if the color of the line is light or dark, if there's 2 lines its positive.

First of all you should always use protection. It's very silly not to use a condom if you aren't on the Pill or any other contraceptive. Then the risk of pregnancy or scares are extremely slim.

Second of all it usually takes two weeks from conception to fall pregnant. After that many women (but not all) will miss a period when it's due. You can also get First Response pregnancy kits that will tell you before you miss a period if you are pregnant.

Take another pregnancy test, if this is positive then go to your doctor.

If it's negative don't take silly chances again if you aren't on the Pill.
