Please help me

I live in usa and my husband is in Norway right now. We got married in 2018, last months i was with him( I visited him for 2 months and 3 weeks) we really want to make baby now, we both think we are ready now. I was with him from February till april 24th and all those months we had unprotected sex but no luck. I used to have irregular period before and i was taking birth control pills but I stopped taking pills from January. After January i have been getting period on time. We had sex on april 22, and 23 after my last period. On april 24th i left him in Norway and came back to USA. Today is 9 days late for my period. I took a test today hoping I might get positive but it came negative (I tried on two different test). I am having mild cramp, mild pain in my breast and mild lower back pain. I had headaches for 2 days now I don’t have headaches. I don’t know what should I do, I m very stressed at this point. Me and my husband both are praying that i m pregnant this time. Please advise what should i do now?
