This is the first dark line

So this is the first darkest line I have had on a pound land opk, I am on day 34, is it to late to ovulate now? I breastfeed my toddler so not sure what my cycles are like only had one period since having her and that was 12th feb.. from this test I think I’ll ovulate in the next few days because this is the darkest I’ve got on a opk. But I’m not sure if it’s miles to late to ovulate as I am cd 34 already
