My cycle is 28 days and I tend to be one day late but now I am four days late. My boyfriend and I had sex when I just got off my last period and he used a condom and also pulled out. A few days later he used a condom again but never finished. Last Friday (i was supposed to start my period on Tuesday) he came on my breasts but it rolled down into my clit but I washed it as soon as possible. I am not experiencing cramps, I usually have terrible ones, or discharge the last few days. I have also been feeling nauseous in the mornings all month. Are my boyfriend and I freaking out over nothing or should I take a test?
