Breastfeeding mommas!! Helpp

Destiny
Okay so i've been breastfeeding for 7 months now, this just started like yesterday, both my boobs are sore, this isn't the kind of sore like the baby isn't latching properly, it's the sore like when I first got pregnant, or before my periods! Which I haven't had sore boobs before periods since I had her. Could I be pregnant?
