To those who have been through pregnancy!

Good morning, I needed some advice! So the last time I had sex was August 13th, and In September I had my period but it came 9 days late. So of course I thought since I came on, I'm not pregnant. Well October came around and I was suppose to start the 21st and I didn't. So therefore I skipped the whole month of October. Still to this day my period hasn't came. Back in August on the 22nd I threw up when I had made it to school and I didn't think anything of that either because I mean I had just had sex the 13th so wouldn't it be too early to show signs and symptoms? But every since October I've been having this milky white discharge and it's creamy. I'm scared to test because of course I don't want a negative 😩. But eventually I will. To the women that have conceived before rather you miscarried or went full term, does this sound like a possibility of pregnancy?
