Birth control interactions

I'm just curious, I known I could ask my doctor but I won't be seeing my doctor until after I need to know this answer, yes... I know I can just call.. busy office.

I was originally given birth control to regulate periods, help with cramps, ect. Not to protect against pregnancy so my doctor never told me if there's any interactions or anything.

I also have social anxiety and was given Buspar (a mild anxiety medicine) to help with it.

After being on Buspar for a year I no longer need it, just for major things.. like my upcoming wedding.. I am very very nervous about standing in front of everyone for that so I plan on taking my Buspar for that week..

Buuuuutttt, for out honeymoon we are planning on having condomless sex for the first time.

Is there any interactions with birth control and Buspar ?? I am suppperrrrr nervous and worried if I should even take my Buspar and risk just having a panic attack.
