How bad are indents on Frer?

So here’s a little back story. I underwent an <a href="https://glowing.com/glow-fertility-program">IUI</a> almost two weeks ago, Monday (22 OCT 2018), i ovulated on the 23rd (Tuesday) and am now 11DPIUI, and 10DPO. I had two very large follicles that were both triggered. I am currently still on 5 mg progesterone. I had a VERY faint line on a FRER that definitely had some pink color to it. I had taken it apart so i could get a clear picture. I will be testing again on Monday, but has anyone been in this situation? And can offer some insight?
