I was on sprintec for 3 years, and recently got switched to trisprintec about a month ago. My doctor said that if I start trisprintec after my break week from sprintec I’ll still be protected. I did this, and also used condoms. Right now I’m on my 3rd placebo in the trisprintec pack and my period still isn’t here. I feel like something is going on down there but it’s just not happening. I have no pregnancy symptoms at all. Is my body just trying to get used to the new birth control? Usually I would have my period by now. I’m young, and don’t want kids. Therefore I double up to stay safe. I would appreciate any response
