any advice?

so me & my husband have been married 8 months, havent got pregnant yet! 🙁 we have been trying, everytime i get my period it breaks my heart🙁 as of right now i am 4 days late on my period, which is a little strange cause im usually regular. i took a home pregnancy test about 6 days ago & it was negative, i’ve had cramping & pain as if im guna get my period but i havent.. i took an ovulation test(just to take it) & its coming up with 2 lines, kinda wierd cause if i was about to get my period, i would only have 1 line on the ovulation test right? any advice?
