How do I take this???

My husband and I want another baby real bad, we have an 7 and a half month old son. We got ovulation tests and I’m just about to be ovulating and I’ve been on the mood for like a week and a half like 24/7!! And he knew we’d have sex starting today for a week straight and see if that works:) but I hate begging him, and most the time he says no he’s tired because he’s working two jobs and idk how to take that. He know and wants a baby too.. should I just leave it alone and quit asking, and if he wants to we will? I get so upset and like sad every time..
