This is my first pregnancy

I tried for years to get pregnant and never thought that I could get pregnant I thank God each and every day for my blessings I have heart failure and diabetes and sleep apnea I get very concerned about my pregnancy I'm only 5 weeks and 5days but I was on a lot of medication I saw family planning and my primary care and I completely stopped taking all my medicine for the baby I put all my trust faith worry into the Lord knowing that he got it I had a ultrasound the one that goes inside you she told me she couldn't see the baby in uterus mayb because I was 2 early but they schedule me for another one Monday I'll be six weeks I'm scared they won't see it again I just got to have faith that God got this
