Am i pregnant?

Andre

So, on 8th October i did mutual oral sex with my bf where he ejaculated in my mouth but it was just a litte and i spat it/ swallowed my saliva, then i kissed my bf and he went down there.

After this i panicked cause i was afraid that i could be pregnant. I waited my period and it came, normally like always, but i read somewhere about a woman that had her period and still was pregnant and I stressed a lot. This month my period came earlier ( like 4 days than normal) it was lighter and the flow was less. At 4th day it stopped and the other day it came out a blood clot with tissue and period started again.

It stopped again and this morning i had brown discharge.. and 3 hours later again ,my period...

I'm not pregnant right? I mean i had 2 periods

This is weird but its still a period, right?
