Hello, not sure what your question is... Cervical mucus is supposed to vary throughout the month, around ovulation it should be the consistency of egg whites and then for lots of people it gets kind of tacky during the Tww... If your not having good egg white cerivcal mucus (EWCM) around Ovulation then you can try a sperm safe
I agree with bny...if you don't have enough cervical mucus around ovulation, preseed could help. It's basically a sperm-friendly lubricant that mimics natural cervical mucus.
...oh, I just saw that you're in Belgium. I'm not sure if they sell preseed there. They might, though...you can probably find out on their website at www.preseed.com.
Green tea, grapfruit juice and baby carrots are also supposed to help. So is salty foods, since your body needs salt to produce mucus. And don't forget to drink lots of water!
