I started going back on birth control last week, and I'm still taking it but today I just got this really itchy sensation down there, and it's not around my vagina, but its inside. Me and my boyfriend used a condoms the last time I was there which was last week, and I haven't seen him since now, so I doubt that it's somes sort of STD, and we are faithful to each other so we don't have sex with anyone else but each other, I'm starting to think it's the side effects of the pills I'm on, which is Aubra Levonorgestrel and Ethinyl Estradiol Tablets, 0.1mg/0.02 mg. Any thoughts?
