Breastfeeding during pregnancy?? Help please!!

Okay so my youngest is about to be 10 months old and we're trying to wean him off of it currently but so far its not going very well. Today we got a bfp! I want to be as healthy as i can for the pregnancy so we don't miscarry again (had a chemical on thanksgiving). Is it okay to breastfeed my 10 month old while I'm pregnant? Is it safe? Thanks in advance ladies! Have an awesome day!
