not sure if pregnant or just hormonal?

My last period was march 12th, its now May and I havent gotten my next one. I get what feels like period cramps every once in a while but they come and go. I feel very hormonal I'm rarely this emotional even during pms and it keeps feeling like my period is around the corner but it never comes. I've never been like clockwork but I cant remember the last time I actually skipped a month. I've noticed that my skin has gotten very dry the last couple weeks but I havent changed my routine. I'm also urinating a healthy number of times every day. The last week or two I've also noticed I've been more fatigued than usual even though I'm getting a good amount of sleep every day and not doing very strenuous activities. I havent taken a pregnancy test yet but I believe I should. Should I be concerned that I'm pregnant?
