what the heck is going on!?!?

Sorry this is a rant, probably best suited for a journal entry. My body is literally going wacko.
We went out Saturday night to our friends house, I'm friends with the girl more so and Jase is friends with her partner, so you get the picture :) We're friends with them both lol. Anyway they have two kids one is only 3 weeks old (awww) their eldest two and he is a Mr. CUTIE! Her sister was there with her two children her youngest 3 months old (yes, AWWWW). I clucked, cooe'd and dotted over them all night as you'd imagine even the older ones, I seemed to have one of them bundled in my arms. The girls kept telling me how much of a great mother I'll be :) I hoped so, I also just wanted to hold them incase oneday I can't hold my own. Anyway, not the point.  My pain set in.. I took 4 tramadol (I was also driving so I tried not to take more just incase, although I know I would have been fine, they do next to nothing) and just sat down with the babies. Pain so so hurting..it eased off after a few hours, enough that I felt I could stand up every so often and rock the babies to sleep or give them a burp after a feed :) (and then recieved a spew! lol).  Yesterday though I was awake for all of 3-4 hours total. I felt like I had 0 sleep and all I wanted to do was catch up on sleep. I got up at 9am went back to sleep at 10.30 woke up at 12.45 to Jase calling me, slept untill 3.30 when he woke me up once he come home from work.. stayed up untill 5.30-6 and fell asleep on him watching movies. He wanted to go see some friends (with me of course), our friends try so hard to accomodate for me, making up ebds with the tv in the room, or a little bed on the couch, heat packs, drinks, food etc. But I justed wanted to stay home...and you know what, I cried, I cried and asked if we could stay home like a 3 year old. Emotional? YES =| I was so emabaressed. Jase just called them up and said Im not well, we are staying home. I felt like crap, normally, I dont care if he goes out, but i wanted him home last night, my body ached, my ribs ached are were so sore, my chest felt heavy, my uterus hurt. I had a slight headache and I easily could have fallen and slept on the floor. What is going on with me?  I don't know.
I know my period is due - but...it's never on time. Oh who knows, but yesterday knocked me around hard! =(
