Please help anyone with experience I’m really driving myself crazy

SO surprised me on Xmas by not pulling out, that was the last day of the fertile window so not likely that it would have happened but then my period was supposed to come yesterday, in the am i had very light spotting and then nothing the rest of the day. And nothing today. I’ve had clear discharge. I have done ovulation strips before and it seemed that i ovulate normal. I don’t feel like I’m getting a period. I definitely feel different. But i feel like i imagine symptoms anytime we try so i don’t trust myself. I took a test today and it was negative. Usually my first day of period is lighter but still atleast fills a couple tampons and then the second day it’s extremely heavy. But to barely spot yesterday and absolutely nothing today this has never happened in my life. Anyone with experience get spotting and then negative test and end up being pregnant?? I usually always have extremely regular cycles my entire life so this is just strange. I’d really like to be pregnant. I’ve been wanting another for like 3 years now :(
