What do pregnancy cramps feel like?

So I'm trying *TRYING* not to read too much into my symptoms right now because I don't want to get my hopes up, but I'm a little curious and I think some advice from you veterans out there would help! I've had some nausea the past two days without vomiting, and I've been tired beyond belief, but the symptom I'm really confused about is these strange cramps. My period cramps are wicked awful and surround my entire abdomen. These cramps however are only in the front and they are really low in my pelvic area, almost by my vahina. I've never been pregnant, just started TTC this month, and I'm aware that reading too much into symptoms will drive me over the edge, so I don't need any of those comments thanks :)
