Tender breast during ovulation ?

Took an opk yesterday and the test line was darker. Is it normal to have some tender breast during ovulation? I don’t think I’ve actually felt tender breast during ovulation since my period is irregular and all. Started taking upspring fertility pills 5 days ago. Maybe that could be it?

What are your signs of ovulation and how long do they last? Ttc for a year now 🤞🤞
