Anxious

I’m trying to get pregnant, I’m scared that I’m probably not able to because of my past, I’ve been pregnant before but had a miscarriage then I’ve been trying like 2 months ago and I started spotting and having a lot of symptoms the first month but when I would take a test it would rather comeback negative of invalid then recently I’ve got a heavy period with really bad cramps I’ve been praying before this happened for me to be pregnant and I guess it didn’t work please pray for me for this this time around because I will be trying again thank you
