Pregnant? Just want your opinion....?

Okay, I'm 21 and married, so it's really not that bad, and we're been trying. I have had irregular periods since I was 13, except for the past year I've been regular. I also had very heavy periods. Last month I had a 2 1/2 day period, which was a couple of days late, and it was very light. Like barely pink light. And I was due on the 19th of June, but I didn't start, and I'm not having any of my period symptoms. My lower stomach has become firmer, and according to my husband I'm having mood swings. I'm crying at things I've never cried before, I was watching Practical Magic and cried... I've never cried watching that movie. Also, I've been hungry a lot more and peeing a lot, but I've been mostly ignoring the urge to eat more than normal. I'm doing blood work on Monday, because I went to my doctor 2 weeks after that strange period, and he said if I hadn't started in 2 weeks to do the blood work. It's been a month, I waited on purpose, but I'm just wanting to know ya'lls opinions.
