I'm not due for my period for another 8 days but I've been feeling weird the last few days & wonder if it's early pregnancy symptoms...I've had sore breasts, a metallic taste in my mouth, I'm more thirsty than normal, and my temperature has been elevated (98.8-99). The weirdest thing is that I've been waking up in the middle of the night the last 3 nights & cannot go back to sleep, even though I'm exhausted. I've never had insomnia like that before. I've also been getting over a cold, so I'm not sure if it's all my imagination. Did anyone have similar symptoms before a missed period?
