Anyone in here (which there has to be one of you) that take tri-sprintec? Question for you!

So I missed a period 3 months ago.. I waiting and got a super light one for like one day (but my girls and I were wrestling around..i don't know)the next month and now here we are again on my 6th day of white pills and nothing... Yes I have tested all negative but I'm wondering if maybe I should go get a blood test done. I am NEVER late. Maybe I'm just being crazy. 😂 this is why I HATE the pill. 🤦🏼‍♀️
