Please help me ladies!

Ok so me and my partner have been TTC for 2 years after miscarriage in 2015.. we’ve just kind of went with the flow.. ive been learning my cycle and stuff like that. We decided a couple of month ago to try opks but the brand I bought was awful and was never showing any lines even though I done it 3 times every day... anyway bought a new brand and just took my first one today. Af ended Monday and I’ve got a line this dark already...

I know it’s not positive yet but does this mean I ovulate earlier than expected?! Thank you baby dust ❤️❤️❤️
