Ttc... getting down

Ttc my second child. My husband is 33, I’m 28. Our son is 6 years old. Prior to my son I had never been on birth control. We conceived our first month trying. My husband didn’t want any more kids (he has 2 others from previous marriage.) but I want one sooo bad. Finally after years, we decide to try again for another! It’s been 3 months now I have been off the pill. I thought this would be the month but I have wasted so many pregnancy test 😩

I am currently 3 days past the start of my period and haven’t started. But also no symptoms and all negative tests. We had sex every day of ovulation week. It should’ve happened 😢😢

What can we do??
