Jolivette

Hey girls so I switched over to Jolivette last month, just started my second pack of it a couple of days ago and had spotting around halfway thru my cycle, anyone else experience this? I've also been having cramps for a while now, my period is supposed to start tomorrow & my CM is dry/lotiony creamish... I just have a fear I may be pregnant even though i've been taking it exactly as directed. Anyone else experience anything from this minipill?
