I gave birth on 26/09 and was breastfeeding my son exclusively, I got my menstruation in April and I continued breastfeeding my baby, then my menstruation stopped coming since August, I ve had ultrasound test and pregnancy tests done but there s nothing wrong with me and am not pregnant so my doctor said its probably because I m still breastfeeding my son. So around 27/10 I started feeling nauseous, no breast pain or implantation bleeding neither did urine test shows that am pregnant, I get hungry quickly and get weak and sleepy easily. The nausea is out of control I want to know what may be wrong with me and what I can do to relieve the nausea it makes me feel so sick all the time.
