My sales are low right now, is someone experiencing the same thing as me?

Hi, I’m from Uruguay ( small country in South America ) and in this month my sales dropped like 30% , this is kinda worrying me, I’m doing the same thing as usual , also I promoted discounts to see if sales got better but nothing happened. I changed and tried with another ads too but I’m losing money with meta ads rn.. before my CPR was like 2-3 USD now it’s 5-6 I wanna know if someone it’s experiencing the same thing and if the problem it’s my bussines or it’s something that’s it’s happening to another owners ? Maybe it’s the month? I don’t know. I started in July of 2023 but started to get better at June 2024 and it went really well until now that my sales got a drop. I’m getting nervous by this and I can’t sleep well. If this helps to context, I’m selling women’s cloth and lingerie, mostly to young women
