I can tell you now sweety that you have nothing to worry about at the moment.

Most of the time it takes a lot more than 2 months to get pregnant.

There are some signs you can look out for that you are ovulating, that is the time you want to have sex.

You usually ovulate I think its 14 to 18 days after your period finishes, but thats not always the case.

What you could do is buy one of them ovulation kits which lets you know when you are ovulating.

And another thing, when your partner has cum'd inside you, prop a pillow under your bottom and stick your vagina in the air to try and stop it from coming out.

Sorry tmi :s

Sometimes woman get their period while their pregnant, but wont actually get a positive hpt until their first missed period. I would honestly wait until your due for your next period to take another test. Good luck!
