Anyone pregnant while still EBF a 1 year old?

My little man turns one on Wednesday and has been exclusively breastfed since he was born.  We got our BFP this weekend and are so excited. I'm wondering if any ladies who are still breastfeeding are experiencing any issues? I'm currently trying to avoid what I know is a clogged duct forming and haven't had this issue in awhile ......  thought I'd check in and see if any other mommas are in similar shoes
