Question. Blazing opk cd21

Hi! I’m on cd21 got a blazing opk! I usually ovulate (last 6 years on cd14-15! I hadn’t gotten a peak yet this cycle (28 cycle days) & the only reason I took a test was bc I’m a poas addict!!! Anyways so since I got my first blazing do I start my 2ww even though period is due in 7 days...now 6 days?!?!? And who have ovulated later than normal and became pregnant ??

Has anyone experienced this?
