Spotting

So I’m going to the beach today, & I got my iud in a few days ago (sorry about all these iud posts lol) I’m spotting a little but I wanted to go swimming. Am I able to wear a tampon? I read it’s not good to wear a tampon when you’re spotting but I feel like this is different. My period did end...I think. But I know with the iud sometimes your period can prolong right after insertion. What if I don’t wear a tampon? Will I spot to the point where it leaks thru my swimsuit? Point is, how to go about this 😂 tampon? No tampon? Will the spotting be noticeable? Plz help lol
