Something weird down there

Someone please help me. I know no one is a doctor but I need some type of hint. So I started my period early due to plan b pill and I’ve been having so many side effects from it. And i think my period was only 2 days. Anywho, sometimes I get rashes on my bottom from the pad being there to long. Last night it’s by my vagina part like it’s so irritated.. so I went to pee and it hurts😩 it feels like something is there when I pee something sharp. Not anything that I just can’t handle I can handle it but it just hurts. So I went showered and I was running the shower head down there and a certain spot feels funny it kind of hurts also. So I examined myself down there making sure nothing is there and nothing is down there!! It’s all itchy when I touch it. I’ve been looking up things and it’s saying something about a Bartholin cyst on the opening of vagina wall. It does have a little knot there but it’s not an open sore or anything. I’ve been tested for chlamydia gonn.. everything a few months ago not even that long ago and I was clear. Anyone else had this problem? Wtf is going on 😫 I know obviously I have to go to the doctor but I want opinions. I do think I have an uti though I get recurrent ones but this feels different
