Indent or vvvffl?

hi guys I’m back again, some of you may have seen my post a day or so ago. I originally posted my test just asking for clarification that it was negative. One of the lovely commenters pointed out there’s like a vvvffflll. Ident or vffflll? I would just take another test but my SO & I were TTC for awhile so I’m just bummed out with taking tests. We decided to stop TTC & I got an IUD. I have a ultrasound 1/18 @7:40AM to see if my IUD is in place, so I’m just going to wait until then to see if there is a bean in there or not. Wish me luck please.
