HELP!!!! Virgin but scared of pregnancy!!!!

It all started with my last period. I just turned 17 years old in July and my period for the month of August was two days earlier than expected it was expected on the 21st of August but it came on the 17th and it lasted for the normal 5 days. Well my period that time was lighter than usual bc my periods are usually heavy but not too heavy and this time my cramps were dull and I wasnt in much pain as normal. My period ended and I logged it in on my period tracker and I was expected to ovulate 3 days later.

I've never payed attention to ovulation or the symptoms before now and it's a little confusing I'm not sure when I actually ovulated, I've had some twinges and mucus with the common pelvic and lower back pain but that's it and according to my tracker my fertile window ended yesterday Sept. 2 and started August 27 and my other tracker said I ovulated August 30 (cycle day 14) but it is now Sept. 3 and I'm a bit dry down there but when I pee and wipe there is a bunch of ewcm. I have 4 tracker apps and they are all giving me different dates for my next period (either Sept. 11, 14, 15, or 16).

Now here is where things get tricky. After my period ended my body is different and I have felt different. I've been a bit more bloated then usual and I have been SUPER gassy along with burping. During the days of my "fertile window"' I had spotting for half of the day which has NEVER happened to me before but I wasn't in pain. Now I've noticed that my boobs are heavier and they seem bigger also my areolas are puffy and they seem darker and my boobs aren't fully sore but the bottom/underneath of them feel a little tender. I've also had some lower abdomen cramping but it was slight and dull. Now I'm having a great amount of ewcm. I'm not sure if my mind is playing tricks on me or if my worry and anxiety are just making me notice these things but I have been stressing for weeks along with crying alot and I just haven't been feeling like myself bc I'm sooooo scared, I am a virgin and I've never touched a boy and a boy has never touched me plus i have never even had a boyfriend I'm not at all sexually active so I don't know why I feel this way. I just started my senior year of high school and I can't even enjoy myself because this has been on my mind, I'm literally on Google 24/7 searching everything I feel and it's not helping. I know this is alot but PLEASE tell me im crazy and that this is just all in my head...
