Any advice or similar situations in the past ?

I usually always have a 28 day cycle . I was supposed to start on the 27th , glow keeps changing my ovulation date when I have to document another day of my missed period . At first I was supposed to ovulate on the 15th . Which would make me 15dpo .  I'm on cycle day 31 . 
Pregnancy test yesterday was clear negative . 
My boobs always hurt for 3-7 days before my period . Nothing at all this month . I am bloated but I am also pigging out with my boyfriend too (we are relaxing at the cabin) so that's normal . 
I have been pregnant when I was younger . I was 17 and I just knew , I even took a belly pic the next morning. I had the worst case of stomach sickness . Nothing could help I even had to drive from point a to point b with a plastic bag to throw up in. 
So i don't feel pregnant .  But I also don't feel my period coming . Anything like this happen to you ? Were you pegnant or not ? 
I also want to note that I am not trying to conceive . I got pregnant before on birth control taking it faithfully for years . I stopped . Just try to have sex outside of ovulation days . 
It wouldn't be a bad thing , just not pushing for it
