Yay guys I get to start birth control pills today (seriously happy)

Well my doctor prescribed me trinessa 6 months ago and I was on for 3 months and off 3 months to make sure I was going to go back being a normal person with a normal period. I just got my period 3 days ago and I'm a Sunday starter. I'm taking my first pill today and I am excited. The past two days my ovaries have been killing me, cramps, nausea & pain. Long ago I was not waking up in the middle of the night with sharp pains and trying to stand up so I wouldn't bleed the bed. I am actually very excited to be on the pill, it has some side effects but those are small compared to what I am experiencing now. My doctor still wants me to go in for an ultrasound to make sure everything is okay. This will be my third one because prior to the Bc pills I had an ovarian cyst and my uterine lining was thick. I just wanted to post my excitement to be on the pill until I am ready to start a family 🤗
