not sure if i am may be pregnant. i had 2 miscarriages 8 years ago and i know I don't show the normal signs for morning sickness and stuff. really the only sign I show is no preid but that's 2 weeks away and to earlier to test. I have been tired alot the past week, along with a sore lower back, muscle pain in my knees when I bend, drinking tones of water (like it's a craving), and pooping more than normal (tmi I know lol) so I want to know what we're your early physical sings of pregnancy?
