Hi ladies! This is the test window inside the clearblue OPK. I am not sure if it is a pregnancy test, the instructions don't say anything about it but I have bought clearblue OPKs with pregnancy tests in them before. And is it BFP? I have tested twice with supermarket sticks and BFN. Period one week late but no symptoms and I have been jet lagged which I heard can delay things. Thanks for any advice!!!
