Advice!

So AF has still not arrived. I tested twice more this week with fmu and both were bfn. I swear if I wasn't trying to get pregnant, I would swear I was! I'm always nauseous in the morning but not getting sick, my boobs are gettin more and more sensitive, itchy & I have these blue veins appearing all over them? We are trying for our first and I haven't had any pervious pregnancies. What I'm trying to say is this is all new to me!! I read a few articles that some women just produce low hcg and it takes longer to come up on an hpt. My AF was due on 8/8, it took a little while for my period to regulate after coming off bc, so I know it's late.. At this point I'm just rambling.. Any ideas from you ladies?!? I just need opinions, my poor husband has no idea, I'm just talking circles around him and he nods! Anyway, anything would be helpful! Hope yall are well!!! :)
