PLEASE READ!

I have been on the pill for over a month now well for two years but I stopped for about 2 and started up again! Lately starting the end of January I have noticed that i am not pooping like I use to! So I looked up the symptoms and it said pregnancy. I have no signs of pregnancy and I am suppose to get my period here in the next week so do I take a test or wait to see if I get it? It's freaking me out cause I haven't been able to really poop and my stomach is bloating and hurts please help!
