I was reading back through my journals and threads, and sure enough both times i felt all flu like. Had a headache that wouldn't piss off (not usual for me and i was not pre-e or anything like that). I had body aches like you do with the flu. And was super tired, runny nose, etc. With my first i experienced that about 5 days before my water broke (my water always breaks before labor starts). And it kept on and off (mostly on) until my waters went. With my second it was about 3-5 days before as well. And it got really bad with my second that friday. My water broke saturday morning and oddly enough ALL of my flu like symptoms went away. (Same with DS1).
oh and this could be purely concidental, but the pressure systems (With the weather) have always been right on target and my water would break. Every time there was a pressure system, water broke, and eventually labor started....weird but it was true for me.(and crazy enough this thing was accurate both times) https://www.intellicast.com/Health/Labor.aspx
