am I pregnant?! help!

crystal

ok so. my husband and I had sex a day after my period ended last month. nd then we had sex on the 4th nd the app said that I had a 22% chance of Pregnancy. I've been having cramps on the lower abdominal muscles nd I've been kinda bloated the passed 2 days. my cycle is between 28-32 days. nd I've had all the symptoms of starting a new cycle. it's been passed my 32 day mark and I'm 3 days late. should I get a pregnancy test or just wait?
