Hey ladies , I've been having weird random cramps on and off since Friday , not really similar to AF cramps .. More like a dull cramping pain . I have also been having some weird pinching pains in my side . I'm 7dpo as of today . When I log my data into glow it says pelivic inflammatory disease is the most common reason for cramping ? My boobs are sore though . Which i do breast feed , but it's never hurt before besides the first few days . Feels like AF is coming early .
