If the signs keep up I will get a home test, don't worry.

I am on the pill. My boyfriend and I had sex back in late April and he didn't have a condom. Since then we had sex once (me still on the pill) and he had a Trojan condom.

My breasts have been sore since last Monday and I've been freaking out. My lower back has been sore too. But I haven't had any weird cravings, or nausea or morning sickness. My breasts aren't that sore now anyway. A friend of mine (who's had a number of scares before) says that I have more signs that I'm not pregnant than I am.

Should I not worry about this just because my breasts and back are sore? I'll be having my period next week and I'm having PMS now.

First remember that birth control is not 100% effective, pregnancies can and do happen to women on the pill.

Second, you must also remember that many symptoms of pregnancy are the same or very similar to PMS or PMDD (http://pmdd.factsforhealth.org/)

If you do not get your period when expected, please take a HPT.

Yes, and in addition, most symptoms occur at or around 6 weeks...
