mini pill woes

I'm on my third pack of the minipill and have been using condoms until last night! My husband's sperm burned like hell and I was just uncomfortable the whole time because I don't want to get pregnant anymore. Done with kids! Anyway I spent the rest of the evening stressing - maybe there's going to be a fluke and I end up preggers. This morning I woke up malaised, with a slight headache and just a buncha worry and stress. I take the pill religiously 9pm every night, but I'm still worried!! All I can say is, I love condoms. Sigh.
