Okay, so me and my boyfriend had sex on Oct 16th, 19th and 21st. we used a spermicidal condom and he pulled out before he came. we also checked to make sure that nothing was coming out of it. But for some reason, I started thinking about me getting pregnant. I am supposed to get my period sometime in the begging of Nov. I have been researching stuff about pregnancy and signs and symptoms. But the more I do, the more i get worried. My breasts are getting sore, a typical sign before period. I usually keep track on my cervical mucus for ovulation but i don't remember it. I went to the bathroom today and saw a discharge that was similar but still am freaking out. And i don't know if its from worrying too much but i have been feeling nausea but mostly when i start thinking about getting pregnant. I am really really scared and just cant afford to get pregnant (not money wise, but situation wise) and there is no way either one of us is ready. And i dont know if its just my imagination but to me it seems like my aereola got slightly bigger. I dont know if that always been like and i never noticed till now. and i do get slight cramping but i always do before my period. i just cant calm donw. i am soooo scared. please let me know what you all think. i am probly going to wait 1 more week and if nothing comes up then take a pregnancy test.
