Breastfeeding while pregnant??

Ann • Wife & FT Mommy to 2 little boys and a new baby girl!!
Hi All! Is anyone else still breastfeeding while pregnant again? My LO is just over 1 and I'm 16 weeks pregnant! I'm still breastfeeding him but only upon request once or twice a day. No longer pumping either. He's been on whole milk for a month and doing well. Doctors have suggested I wean from day one of pregnancy but I'm feeling fine doing it and no cramping so I haven't fully stopped, just cut back. Anyone else in same boat and have you stopped or kept going? Just curious how close you continued to birth? Thanks!!! 
Ps, had to add our announcement we took this week!! Another boy 💙💙
