I was apparently worrying about nothing. Just got a call back from the RE's office and my E2 came back at 106. WOO!
Hopefully it means I have multiple follicles maturing and not a ton of tiny ones.
I'm still not feeling much of anything down there, but going to try not to worry about it.
Go back in Thursday morning for just another E2 check again and I stay on 175 until then :)
Forgot to mention that AF is officially gone! It was still smudges on tp this morning, but now... nada. So YAY!
