Hi there. Well, it is good news that you are responsible and having safe sex. That he uses condoms is great! When used correctly, they are pretty effective at preventing pregnancy (and std's). Nothing is 100 percent of course but abstinence but it's pretty much in your favor to NOT be pregnant from condom protected sex. Symptoms of pregnancy, just fyi, do NOT generally occur before your period is due. Symptoms happy due to the pregnancy hormones and these have to build up enough to cause them. Takes some time. Nausea / morning sickness for example starts at about 6 to 7 weeks for this reason. So, you may actually be having premenstrual symptoms right now and would not attribute what you are feeling to pregnancy. good luck
