16 and pregnant ?

I have been with my boyfriend for 2 years and we’ve been having sex for a year now. We have never done it without a condom and he always pulls out. We stopped having sex for about 6 months, and last Tuesday (July 2) we had sex with a condom. I was on the last day of my period. I ovulated (or what seems like ovulation) on saturday night. I started getting the cm that was slimy and clear. I’m freaking out so bad because I’m scared that I could be pregnant. I’m scared if something on the outside of the condom like precum. My period is supposed to come in 2 weeks and I’m just so scared that it’ll be late or never come. I know I shouldn’t be having sex at this age or if i’m not ready for the consequences. I won’t be having sex anymore because it’s very stressful. Do any of you have any advice? I really need it to calm down ): , and Yes. I will be getting on birth control soon.

Edit:

Condom never broke or had holes.
