af due in 3 days

Ahhhh. 3 years TTC, nothing as of yet. I mean we're not strict to the point of opks anymore as that put too much stress on it I felt. We've had a rough past year, I'm so sick of negative tests I tell myself wait it out wait it out until af is late, I never do, in fact then I end up doing 3 in a row just incase it's a faulty one and examining it in the light :( so sad really I know. Just why can't it happen for us I'm so sick of wondering why!! I hoped taking the stress off it it would just happen!! I have a son from a previous who is 5. He is so desperate for a sibling (he crys occasionally at night because the stork isn't bringing his brother!) bloody Disney and its stork film!! 😤😂 anyway we've been BD none stop this month I feel like if this month it doesn't happen it never will :( no symptoms really.. tender breasts but that happens before af anyway, slight nausea nothing to make me feel like this is it.  Who's with me on this dreaded TWW? And anyone who's been trying for a while and had it happen out of the blue? Did you do anything different that month?
