Weird bleeding

Madison

Hey all, so I changed my birth control abt 3 weeks ago since I had stopped gaining weight and could barely remember to take a pill everyday, to the patch which I’ve been on before, for the last 2 weeks I’ve been on my period when I just had one the week before switching. I know irregular periods are normal with swapping birth control but this is my 4th swap due to hormonal imbalance and needing to gain weight and I’ve never had blood as thin as this before or bled as much as this, any tips or ideas on what I should do?
