What should I do?

The day after thanksgiving my boyfriend and I had sex. we always use the pull out method. I know, not the best form of birth control. but my body has negative effects to almost all forms of birth control, and it's not pleasant. we've been sexually active for almost 2 years now, and it's always worked for us, so we just go with it. The day after thanksgiving, we were drinking, and we had sex. well he pulled out but sloppily. he didn't cum in my vagina, but ontop of it. from what I've read it's still very possible to get pregnant that way... well this month has been ruff!! I've been hella sick. strep throat one week. stumuch flue the next. I had a feaver. diarriah, lack of appetite, and nausea for like 2-3 days. also during all of this I had something going on with my vagina. it was like where the clit was was swollen and red, itchy, and just flat out painful! I used some vagicane, and it went away after a week. but I've been VERY wet recently. with a lot of white discharge. it's just been an awful month.... eve says I'm supposed to have my period in 6 days. so I'll see if I'm late.., but if by happenstance I need to get a pregnancy test, my boyfriend brings in the soul income, and I don't have my license. my family would blab to every tom dick and harry.. how do I go about getting a test without my boyfriend flipping his shit? becuase he's a worry wart. And he will freak out...I don't want him freaking out unless I am really pregnant. advice? do you think I'm pregnant? my bladder has been acting up for months. peeing all the time. constant discharge is normal for me, not even sure that is a symptom of pregnancy. more nauseous than normal... actually little to no appetite, but very thirsty... idk, maybe I'm over thinking.
