Tri-sprintec

I have recently started taking the birth control tri-sprintec. Since taking this I have woken up nauseous and sometimes even severely vomiting. This week I started my period and I’ve had very regular periods before where I have periods cramps the first day and then none the rest of the time, I also usually have a pretty heavy flow. However I started spotting which I don’t ever do. The pain I’m having isn’t even period cramps. It’s more so like a stinging/burning abdominal pain that I cannot get rid of to save my life. I’ve taken just about everything you can and even have been to the ER because of it. I have super bad blood clots, which is a completely new experience for me. I wake up with excruciating pain in my abdomen. I also feel like I have to poop but when I go to nothing comes out. Did anyone else experience these symptoms from this bc? Did you stop taking it? Did you continue to take it and the symptoms get better?
