Late or pregnant?

Karli
Hey y'all! So I haven't had my period this month yet, I was supposed to start 2 weeks ago and I haven't had any symptoms that it's coming yet, I spotted a couple of times but that was about it.. I am sexually active with my boyfriend and the only protection I use is birth control and days that I'm not fertile. I don't think I am pregnant, not because I took a test and came out negative but because I have no symptoms whatsoever and I feel like it could be stress but not sure, any advice? Lol does anyone relate? Thanks for the feedback!
