opk first timer

Alexandra

Hey!

I'm so confused - started my first OPK test on Tuesday (2 days after AF ended), visibility see two lines but second line wasn't that dark.

same thing Wednesday... and then second line little less on Thursday and even less on Friday. I have 4 different apps downloaded, <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">Eve</a> says fertile starting today, the others say Monday or Tuesday, and OVulation day predicted for 3/4th but everything is different.

I thought the closer I am getting to OPK the test lines would get darker but now that they are getting lighter I am worried I maybe missed it...maybe I'm just crazy though!

This is our first time officially trying to conceive, I'm so nervous!

Has this happened to any of you?
