I don't know if it's lack of sleep, hormones, or just stress, but I feel like I constantly have a headache! Anybody else feel like that? Have you talked to your doctor? I don't go for my post partum checkup for another 4 weeks, and I don't want to bother them for just a headache, but have mercy, it's annoying! I'm afraid to take anything since I'm pretty much exclusively pumping...
