Is this normal for the beginning of marriage??

We just got married July 7th and fight over everything. We always had a relationship where we bickered because we are very similar in personality however we would end up laughing and it would smooth over before marriage. Now it's awful. We fight all the time and I'm starting to ask myself, what have I done? I question myself if I even love him and I'm feeling trapped because I'm not one to believe in divorce unless it's over a serious issue. We dated for 2 years, broke up for 3 only due to geographical differences, and then got back together for 2 years before we got married so I was certain he is the one. Is this just an adjustment being married and do others go through this? This is not fun!
