Pregnancy Info HOME

Well me and the DH aren't TTC. But I want a child so badly, as irrational as that may seem, and have since I miscarried several months ago.
But I again think I'm pregnant. And while it's probably me just wanting to be so badly that I've made myself a bit crazy, I thought I'd ask just in case.
Whenever I'm home we really take advantage of it, as we go about 2 1/2 months without seeing each other. The last time was the March 7-14, and we had had sex each of those days. Now I didn't realise it to begin with, but Feb's a short month, so it throws everything off. So I think (but my math isn't the best) I might have actually been ovulating.
Anyway, my period normally comes on the 16th or 17th each month, depending on the months, because my cycle is 30 days. Last month I got it on the 17th, and I thought I was late this month, until I realised Feb was short by 3 days, and I got it yesterday, so it seems about right.
Except it's different. I've read about IB, and I don't think it's that, but I'm unsure. It isn't nearly as bad as it usually should be by now, it's neither as heavy nor as painful. It isn't spotting or brown/pink, but it started out that way. I've gone through several tampons, but only because I keep checking, and there hasn't really been too much blood. So I'm not sure if it's IB or AF.
Also - and while this could be my imagination I can't make some of it up.
I've had cramps for days now, and even the ones I've had since I began bleeding, they're all really mild. They're fairly constant too. But they don't feel like the usually cramps, it just feels a bit like pushing, almost, and it's lower down than usual. Some that were worse than the rest went away in a minute.
The first thing that made me consider that I might be pregnant, as I didn't think it was possible first off, was my boobs. I SWEAR they're bigger. They were huge to begin with, in all honesty, so I can't tell exaclty, but I'm near postive. Only one of my bras fit properly, and now of my shirts do. And they don't feel the same, they don't feel bigger but swollen, if that makes sense? But they only hurt when pressure is put on them, or they're bounced.
I've also been really sick, especially after I eat. It's an on and off thing all day though. Today wasn't too bad, but I ended up having some stuff come up this morning. Morning sickness or me being too sensitive?
I've gotten acne, which I never, ever, get. And headaches quite a bit, which I again never get. I've been having to pee quite a bit too, but then I pee more than a normal person anyway. I've had flash crazing when it comes to food, nothing crazy like pickles and ice cream, but just for things I wouldn't normally eat. And I smell things more than normal, but most of them don't make me sick, exactly. I get tired a lot too, but at the same time I'm having a lot of trouble sleeping (which could just be me thinking about this too much).
I wasn't going to write this. I don't want to seem like the crazy girl who thinks she's pregnant everytime she has sex. But I did because I found out something interesting I didn't know about pregnancy, so I know I couldn't make it up. I've been sneezing a ton these last couple of days, and I'm not sickly nor do I have allergies. So after sneezing so much that I though I have sneezed out my insides (that's really how much pressure it put on my stomach) I googled "Sneezing pregnancy" and it came up with quite a few women saying they sneezed a lot in their early pregnancy.
I know this is me still trying to keep my hopes alive, and I probably am not, but I figured I might as well ask and see what people had to say.
