Yes so that sounds like you had your LH surge last night. Generally you’ll ovulate 24-48 hours after getting the surge (so would probably say today). Some women experience a bit of cramping when it happens so if you’ve had any today, that’s probably a sign!
Swimmers need to be there and ready to meet the egg so DTD yesterday was a good idea, if you can do tonight and tomorrow that will give you your best chances of them being there to meet the egg. If you’ve DTD in the last few days, swimmers can live up to 5 days too. Fx crossed for you!
Please ask away, there’s so many fabulously supportive women on here 😊
If you’re new to OPKs, you might find using clear blue smiley face ones easier to start with as they’re clearer to read but they are so much more expensive but it helped me get used to them before moving to the strips
