Should I be worried or is this Normal?

I have been in a very serious relationship for awhile now. We aren’t trying to have a baby but we aren’t using condoms. (He doesn’t finish inside me) but my period is usually 7-12 days long never less. This month my flow was 5 days and the first day and the last day it was super light. I do hormonal therapy (taking progesterone supplements because I don’t make them naturally due to extensive use of high dosage birth control) I have notice an extremely large amount of creamy white discharge over the last day or so. There’s no smell to it. Should I be worried or is this completely normal?
