Beyond confused!

So , currently I am waiting on my period . I have no sign of it and I feel completely fine ! My cycle varies usually between Cd27-31. Usually I spot before and then get my period but I haven’t spotted yet . I have taken two pregnancy test , both came out negative ! Usually I don’t have any pms symptoms until it actually comes , but I’m really getting worried . I’m anxious to know because I don’t want to be pregnant even though I’m sexually active. Here’s the thing , my cycle last about five days and things got heated and I had unprotected sex on Cd7 . Realizing it was wrong we stopped but at the same time it’s too late , unprotected is unprotected no matter how long , however he did pull out. I ended up having sex during my fertile window with protection and pull out method . I watched and was totally aware of his ejaculation. Even if my cycle is 27 days long I usually ovulate between days 13-18. I just really need some advice. I have started a new job and my sleep has been off and on. But I honestly don’t know why my body is acting this way. I’m so afraid ! 😕 (btw I took a blue and a pink dye test , both were negative as mentioned before) also I did take the test early in the morning .

Circled days are days I had sex , all protected except the 10th .
