Way to turn off period on app during IVF?

Jenna

I’m currently waiting to do a transfer but my doctor has had me on birth control to avoid periods for about 3 months now so we can plan the cycle accordingly. Just wondering, is there a way to turn off periods while your status is on treatments or do I just have to keep saying my period is late on the chart. Seems silly there wouldn’t be an option like this as many women have to shut down periods during treatment. Thanks for any replies!
