Probably Pregnant

[TLCsMommy]

I guess I will start from the beginning:

I had my last AF on Nov. 22nd 2011 - it lasted for about a week and a half. Hubby and I DTD a few times as soon as AF was done between Dec. 4th and Dec. 6th.
On Dec. 14th I had started bleeding. But it wasn't normal red blood. It was a little thick and a brownish pink color. It only lasted for a couple days. DH and I just thought that it was AF coming again, but it didn't feel like it. I just chalked it up to my body trying to get back on track after BC shot in May or 2011.
On Christmas Eve, around 11pm I had what felt like AF cramps..very achy feeling. That happened again around the same time on Christmas day. We didn't really think to much about it..thought it was probably a stomach ache from all the goodies we ate that day.
Up until New Year's Day I didn't really notice of symptoms except myself being extra moody. On New Years Eve hubby and I went out to celebrate, we both a a few drinks and jello shots. Normally I can hold my alcohol pretty well, but on this night I couldn't. I was extremely tired within the first hour of drinking (2 or 3 drinks) and by the end of the night I was throwing up yesterday's lunch. Since then I have noticed that I am always hungry and nauseated off and on during the day, Constipated, and my gums have been bleeding for the past couple weeks. I am really bloated, and still have cramps every now and then. DH just pointed out yesterday that my boobs were bigger, they've been sore for a while but I didn't notice them being any bigger. I have noticed blue veins on my chest and down my arms - I have never seen that before with my other 2 boys.
Do you ladies think that this could all be related to pregnancy? DH and I are waiting until AF is late this month to test, just want to know if anyone else thinks that this could all be pregnancy related.
Sorry this post is so long, I just wanted to make sure that you all knew my exact situation.
Thanks!

I should probably add that I have been peeing every time I hear or think about water.
