Yes that's the best thing to do
Hi, if your partener and you didnt touch meaning there is no way pre c u m could have gotten in you than you are probally not pregnant. There are a couple things that can cause you to miss your period, anything from new medication to gaining or losing weight can cause you to miss it. The best way to find out is to go to the doctor and tell them whats going on they will prpbally do a pregnancy test and take blood. Hope this helps a bit. Good luck to you.
