Why is my feeling a little weird?

I haven't been having recently. I have been using m vibrator. A few nights ago, I put a condom that I got from my college on it (not the brand i use) and enjoyed myself. Now for the last couple of days I have like this sore feeling. It was red but it went away overnight. I used my feminie wipes and it feels better. I dont have any odor. I also dont have any yeast type stains or anything. Istart having brown residue like I am getting on my period. My period recently skipped a month too but thats normal for me. My sometimes feels like i have a tampon in it or how i felt after the first time i had .Almost as if I have to push something out . Also I fingered myself last night I had the bleed residue and some small little piece that look like leftover toilet paper. I starte using new toilet paper too. It's softer and thickr. Usually we use cheap stuff from my mom's job. Also My been drier. Like I use to be able to get wet and a thought. Now it involves a lot more work I made a doctor's appointment already. I just wanted more opinions
