Help! Pregnant and Breastfeeding

Sh

I am currently 6 weeks pregnant and breastfeeding my 13 month old. I have had basically no symptoms other than fatigue until the past week. Nursing has become so painful. My boobs don’t hurt but my nipples are so so sensitive. I feel like I could hurl or cry every time she latches and it just feels so uncomfortable. (Nursing has never been painful before now). Any other mamas have this? Anything I can do to make it less painful? 😖
