The pill💊

Adria • LG(B)T 🌈 Love to help others💞
My doctor prescribed to put me on birth control because of my period. During my period I experience cramps for up to 3 to 4 days sometimes nausea and lower back pain, and I use about 4 pads a day I bleed pretty heavily and I think I have endometrosis. Since I'm going to be on the pill soon can anyone give me advice or information? It is all appreciated 💞
