Symptoms??

I had sex on Tuesday (17th) (protected) and he thought the condom broke when he pulled out... mind you my calendar said I had a 22% of getting pregnant that day. I sat on the toilet and stuck my fingers inside me and nothing was there but a little bit of white discharge. The next day my stomach was bubbly and I felt a little lightheaded if I got up too fast. But I’ve also been stressing aloooot lately. My period isn’t supposed to come until the end of the month. Yesterday I got some thick white discharge in my panties .. but my stomach still feels a little crampy. <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">Eve</a> (the app) said I was ovulating the 12-18 but I don’t remember anything in my panties around that time.. but now I see discharge now. Although today I don’t see any. Do you think I’m pregnant?
