Just wondering!!!

Samantha
I'm new to the app I have been logging for a couple months now! AF is due on Wednesday and when I went on today it says to take a pregnancy test???? Should I take one even thought it's telling me there is only a 3% chance of pregnancy??? We have been TTC for two years now and I had a MC in March I don't want to get my hopes up!?!?!? Please some advice??
