I have a period question

Before I ask, I am on birth control (the patch.) I had what I believe is my period the 30-2. But it was weird. 30th was only spotting. First was just light flow, barely enough to need a pad. The 2nd it was just spotting again for like half the day. No clots, no cramps… my periods are usually about 3-5 days and usually pretty heavy the first two days with clots. This month was just off. Also before my period I always get horrible PMS (nausea, bloating, cramping, etc.) this month I was just nauseous and really sensitive to smells and certain things I usually LOVE tasted horrible. I figured that was just PMS. But I have NEVER had a period like that before. 🤣 anyway it usually tends to go away after the first day. This month?? Nope. Im still so nauseous I can hardly eat, my breasts and nipples are still sore, and peanut butter still tastes and smells like ass. 🤢 (I LOVE peanut butter and Reese’s.) I already left a message for my doctor about it. Would what I had be considered a period? My OBGYN did say the birth control could be dwindling my periods down, which I wouldn’t mind. Oh! And also I’ve been craving red meat like crazy. I don’t even eat red meat like that… but judging from bloodwork I had done at the ER Friday, it seems my iron is low, so that is likely the culprit there. That period just kind of confused me. I’m used to pretty heavy ones. Not spotty, light, spotty.
