I'm also having the same symptoms. Hot & cold flashes, especially at night and also needing to get up and pee during the night - 3 or 4 times at night at least. Had a miscarriage about 4 weeks ago, so would be surprised if pregnant again already.... but of course I'm dying to know. Perhaps reading too much into all of this..... I didn't have these flashes last time around. If not, what could they be?
