Advice?

My husband and I have been trying for the past year to have a baby, with no luck 😔 we started using Fertilaid for men and women and I stared using Fertile CM also about 3 months ago. My periods are very regular and are never a day late. Usually I have symptoms about a week before but this month it’s different. I have been feeling nauseous and even vomiting in the mornings and early afternoons and haven’t been able to eat a lot of foods I love! I don’t want to read to much into tho Incase I get another BFN. AF was due to start yesterday and still nothing and my cervix has been high, firm, closed, and wet. Has anyone else experienced this and got a BFP? I’m nervous to test, thinking to wait a few more days before I test. Any advice will be welcomed! Thanks!

UPDATE: AF appeared this morning, currently trying not to cry all day 😔
