So I had my 3rd 9 months ago. He is currently breastfeeding and in the last month or so has started to eat soilds. I started my period around his 3 month mark. Got it every month after that on time. Which is usually the 6th, now this month (May) I still have yet to get my period. I'm not on birth control due to some medical issues and limited options when you choose to breastfeed. I've taken Pregnancy test since the 6th and all have shown negative. I've been getting dizzy spells, cramps and my milk supply feels like it's going up? Is it possible I'm pregnant? I've heard that when you BF it can result in false negatives? Has anyone experienced this. Please help.
