Breastfeeding and pregnant

Ashley • Baby girl born April 20,2016 #A.A.O

I'm almost 8 weeks pregnant with my second n so far I've had morning sickness that included diarrhea (sorry tmi) I still breastfeed my almost 11 month daughter.

Every time I breastfeed her she will get diarrhea as well.

Is this normal idk what's going on. Advice will be taken thanks.
