December 16th ?!?!?!

Ok so my last period started December 16th and ended on dec 22nd. Since then I did miss 2 pills and we did still have sex. Not saying that did it but it's possible. I have had cramping on and off, light dizziness, back pain here and there, sore boobs and some bloating. Now I get a lot of these symptoms before and during my period also. I have so many thoughts and emotions going through my head it's craziness. It would be such bad timing, we are having family issues on my boyfriends side and we aren't financially set. 
What do y'all think of this and should I test? If so, when would be a good time to test where I shouldn't get a false positive?
