I just wanna state, that when I was breastfeeding my daughter, my doctor cleared me while pregnant to keep on doing so and I breastfed both my son and daughter for a year each, that was two years straight! It's up to you and your doctor. I didn't have to ween, so always take your doctors opinion mixed with your questions! Good Luck!
Try an ovulation predictor kit. If you are planning on becoming pregnant again so soon you should quit bf and start formula. Its better for the new pregnancy. Im am sure there has been woman that have bf during their new pregnancy and everything was fine, but the doctors will tell you to ween once you become preggers again. Good luck!!
Try basal body temping...check out the website for fertilityfriend...Good luck!
You should be ovulating. I was breastfeeding my daughter, when she was 3 months old I got pregnant again! And I went 2 years without a period. So badically just bd every other day for now, and pay attention to your body! Look for the ewcm and you should be good to go!
