Pregnant and Stopping breastfeeding

Hi Ladies,

Any advice on how to wean from breastfeeding. My son in 17months and bf's 3 times a day. The nap feed is easy to eliminate but I'm worried about morning (for me ... being full) and night for him. I'm 6w3d pregnant and have been bleeding so if I stop breastfeeding it may help. I had an ultrasound and everything looked good and my hcg doubled. The bleeding obviously scares me so was going to see if I stop breastfeeding if it makes a difference. Im not sure how to stop of how long it takes.

Thanks!
