Birth control giving me dryness?

Savannah

So I recently got Nexplanon about 2 weeks ago and I’m sure it’s already working because I’ve been getting cramps and I’ve been spotting more than usual. But the last time I had sex i seemed not as wet as I could get. I wanted to I was super into it but I wasn’t as wet as I used to get before the implant. Could birth control be the cause?
