So I have very light periods is this normal on my first day I don’t fill up a pad at all and not even half way .. Second day I can start wearing panty liners and 3-4 days wear just panty liners and I’m off my period on the 4th day ! I’m not complaining just want go make sure it’s normal ! Would this be why I’m not getting pregnant? It’s my 3rd month out!
