Should I get worried about a pregnancy?

This is my chart for this cycle. My copper IUD was getting expulsed (without me noticing). My ObGyn took it out on CD 16. Since then, we've been using condoms and/or withdrawal. We are TTA. My LP was on the short size so last cycle I decided to start drinking red raspberry leaf. My cycle is usually 25-28 days...glad that my LAP is getting longer but did not have a 30 days cycle since my teen years. Should I get worried?
