Pregnant maybe?

I had sex three days ago. We used a condom though, and it didn't break. And as far as I know it didn't have a hole.
Do you think I will get pregnant?

No, if the condom was on properly then you will not get pregnant, however if you think you have then its best to visit your local GP and get them to check.

No

If you use condoms, they're 99.9% effective against pregnancy and STDs. When used properly, they're the most reliable contraception around. Relax, I doubt it's something you need to worry about

There are condoms, and there are condoms. American-made Latex condoms recently purchased are 99.9% effective against prevention of pregnancy. Lambskins are a little less effective, so those should be avoided. Lubricated condoms are usually lubricated with a spermicidal agent such as Nonoxynol-9, which also helps prevent pregnancy. Additionally, Nonoxynol-9 displays antiviral activity, such as against Herpes or AIDS virus. Condoms lose their protection as they age, and they CAN break on occasion. It's not frequent, but they DO break. NEVER re-use a condom; that's an invitation to condom failure.

I highly doubt that your pregnant. I was the same way my first time when I was younger. But also remember like the others said, They are only 99.9% effective. As long as the condom didnt break, there wasnt a hole in it, and he didnt c*m inside you I believe that your okay. Also make sure that in the future you try to prevent sex when your ovulating.
