period gone after sex????

I have a normal 28-31 day cycle. Except this last time I got it on day 34 smh. My periods always last 7 days. Anyway, I had sex yesterday on day 3 of my period. I bled during but after, it dissapeared. Thought it'd come back today but still nothing. 
I did read that orgasms can make you shed faster and end your period sooner but girl I didn't orgasm so where's it attttttttt? 
Is this normal???
Does this mean I'll ovulate sooner ? 😰
Thank u for your help!!!  :)
Also sorry I posted this in 3 diff forums- didn't know which one it pertained to. Thank u!! 💕
