I am currently experiencing symptoms of nausea (normally accompanied by hot flushes), extremely low energy & feeling dizzy and faint especially after lightweight exercise. I have a 4month old and felt similar in early days of pregnancy so I have taken a pregnancy test this morning which came back as negative. Up until last week I have been exclusively breastfeeding but I am now supplementing with bottles (2/3 a day) I wonder whether it’s a hormonal change and if anyone has experienced a similar feeling when reducing breastfeeding.
