Stressed out or pregnant?

Sabrina
Long story short I was supposed to get my period today (periods are irregular but they occur at the beginning of the month usually) and I haven't. I've had regular pms symptoms (sore boobs, some cramping bloating, white discharge) but it seems like it's not going to be coming soon.
​On top of this I've had a super emotionally and financially stressful month. I am sexually active. Always use condoms and most of the time he pulls out before finishing. There have been no leaks or tears (that I know of) but im still really paranoid and freaked out, could i be pregnant?
