Ovulation

This morning I took a clear blue digital opk. No smiley it was negative. I took another at noon, it was negative. Took another at 5pm after work and it was positive.

My question is is it to late to get pregnant if I already feel Ovukation pain??? I wasn’t able to bd till I got home almost the same time I got the positive opk and we did not dtd last night???? Please tell me I’m not to late..............
