Have any of you mamas been sick after birth? I had my son 2 weeks ago and my body aches and I get a bad headache sometimes I've had it the past couple days. I haven't gone to the doctor cause I feel better in the morning. But then I sometimes get it again. My boyfriend said it's just my body changing from all the horomones. What do you think?
