I had sex last week for the first time. we used condoms every tin and i have been nervous about pregnancy. could i be pregnant?

Safe intimacy: Condoms are pretty reliable in preventing pregnancy, especially if used properly. Check out http://www.cdc.gov/reproductivehealth/unintendedpregnancy/contraception.htm for further information regarding contraception. Make sure to be consistent with condom use. As far as pregnancy, if you had breakage of the condom or forgot to use one, it is possible, but too early to tell. Hope this helps.
