Sudden extremely high sex drive. Should I be worried??

So i wouldn’t say my have drive is high. I masturbate like once or twice a month. I usually start getting horny the week before my period then I get super horny and have the urge then when I have the time I masturbate and that urge is relieved until next month. A few days ago I was horny. So I masturbated. Normally I’d be relieved right after but later that night I was still horny. The next day I masturbated again cause I was still horny and then the next day. That’s 3 days in a row which isn’t usual for me. THEN today, here’s where it gets weird. Today at work I was SO horny all day. I couldn’t stop thinking about it. On the drive back even the feeling of the seat vibrating under me was making my pussy tingle. The feeling was so intense I could hardly focus. I couldn’t stop thinking about sex and dick and every man I saw I low key fantasized about fucking him. The tip of my clit was becoming like kinda sore?? Bc the feeling was so intense I just wanted to rub myself right there in the car. It felt like a heartbeat in my clitoris it felt like I was gonna cum right there without even doing anything. I even thought about going in a public bathroom to relieve myself. Then I got home and had a shower and relived myself normally lol (best orgasm ever btw) but my question is WHY?? it’s so weird that I got THAT intense while out. And not only that but I was horny the 4th day in a row and I had already masturbated 3 times that week. What causes sudden spike in sex drive does anyone else experience this?
