How To Switch From Mini Pill To Lo Lestrin Fe Without Any Adverse Effects?

Good afternoon! I am currently taking the progesterone only/"mini" birth control pill. I am no longer nursing, so I am switching to LoLo Estrin Fe. My question is, do I need to finish out the current packet of the mini pill (I have 6 pills left) ? Or, is it ok to start taking the LoLo Estrin Fe today ? thank you!
