Birth control while on antidepressants

Ash
Does anyone else that's taking antidepressants/anti anxiety medication have any unique experiecences with BC and the side effects. I take 20mg of lexapro and was hoping to get on BC ASAP but was worried that it might have a bad interaction with my current medication. any advice? 
Ps. I do plan to consult a my GP but my mum always gets involved in my visits to my regular GP and I would prefer to keep this private
