Would the 24/5 be a good guess at ovulation ? I’ve had some light spotting yesterday and today ?

Update !! So af showed today and I have just taken this !! What is going on has anyone else experienced this before?? Bottom one was just water as sceptical tests were bad

If I have ovulated could it still happen for me ??
