I just want a baby so bad...

My fiancé and I have been ttc for 5 months now. On Saturday morning, I took a Walmart brand hpt (top test)and got a faint line. Yesterday I took an FRER (bottom test) which looks negative to me. I guess the top one was an evap line. I’m heartbroken and so tired of negative tests while everyone around me conceives with ease. My period is currently 15 days late. Advice or encouraging words would be appreciated, as my heart longs to be a mother more than anything.
