ever since I started birth control 2 1/2 months ago, I started noticing an uncomfortable feeling in my vagina. it doesn't happen everyday, but it does happen often and when it hits I just want to stop what I'm doing and lay down and not be around anybody. it does not itch, it just feels irritated and uncomfortable. I have protected and unprotected sex, but I he never finishes inside of me. he's only ever been with 1 other person and he's my first. I'm not sure what this is and I'm worried. I'm 21 and my family has never been open and talked to me about sex or anything, that's why I get my birth control online. what do you think this is and what should my next steps be? I don't want my dad to find out about all of this.
