Ok, I usually start around the 1st thru the 5th. This time I didn't start until the 10th. I'd bleed then stop, then start again. My breast and nipples are really tender. I've been constipated and certain smells of certain foods make me wanna puke. I go Friday to an obgyn, but was just curious... Could I be pregnant? I had a miscarriage 9 months ago because of a car accident. I bled during that pregnancy as well. My hubby says certain smells make him feel nauseous too and he's having moods that he can't explain the cause of.
