Positive OPK for 6 days

This is my first time positing but I need some input! This is my 1st month using OPKs ( easy at home brand) Last Tuesday I felt quite intense cramping and bloating.. and came home to take a test.. which happened to be a definite positive.. since then I have continued to get bright tests for 6 days and it doesn’t seem to lighten up! Has anyone else experienced this? Does this last test look positive?

This was Tuesday’s positive OPK

And this is today’s test!
