No Period.. Negative Test

I normally and usually get my period every month and I am a heavy flow kind of girl. I have a 7 day period. The symptoms I get are sore/tender breasts and nipples, bloating, painful cramps, and lower backaches.. So, my last normal and full period was back in the middle of December. Last month, I spotted off and on for 7 days. No period symptoms, but only bloating and very faint cramps/ light pressure in my lower abdomen area. I figured I may have experienced implantation bleeding but tested a good 8 times and all came back negative. This month, I am currently spotting again and no period symptoms again. I only see the light pinkish to brownish blood when I wipe. I’ve noticed that it itches around the top of my vagina only when I touch it. The itchiness is not around my vulva or in it. I have not experienced any of this before and I just wanted to know if anyone might’ve experienced this either or might know what’s going on with me?? Could I be pregnant? Do I have some kind of infection?

Any info would definitely help
