Ovulating so late in cycle

Lyndsey ❤️ • Baby boy born 13th March 👶🏼 35 uk

I’m on cycle day 26 and finally got a positive opk? Normally I get them around 17 but my last 2 periods have been a lot more heavy and lasting longer! Last 2 cycles have been 36-37 days long, am I actually even ovulating do you guys think? It’s all so very confusing xx
