AF are u here or are u not? U can't have both

So my period was suppose to start today. It came in the middle of sex yesterday morning. It doesn't usually come early but bc we were having sex I just assumed that was why. Since we r on vacation in Florida I put a tampon in and went about by the pool. 2 or three hours after I put in the tampon I went to change it and there was only a tiny bit of brown stuff on the tip of it. I put another one in and when I took out the second one there was nothing on it. Figured it was bc my period wasn't really suppose to come until the 15th, today. I put on a pad after the tampon had nothing on it and I was done swimming. This morning the pad still had like nothing on it. Just a tiny little dark brownish spot. So I put on a panty liner and only a little spots but, when I wipe there is nothing. I've been so regular my whole life and its prob just af taking her time coming but in my mind I'm kinda still hoping out hope that I could be pregnant. TTC has been making me more crazy than I regularly am 😂🤦🏼‍♀️😫
