so me and my gf (aged 18) slept 2gether (both first time) 3 months ago.

she said she had some bleeding a few days after, but it only lasted half the amount of time her normal period would last for.

shes really worried now that she might be pregnant.

we did use protection, but shes not on the pill.

shes going to try get a test in a few days.
but i just wanted some advise from you guys.

thanks in advance
