Excited and scared

A year ago today I was pregnant but I miscarried in November 2018 , 3 months later I became pregnant again but this time I only had the placenta and no embryo . It has been a rough 5 months to want to try again or even think what would happen if I were to become pregnant again. Well I’m here to say it I’m 4 weeks and 2 days I’m so excited but nervous at the same time like what if I fail this pregnancy again , like what if I can’t carry full term ; I have so many what if’s 🤦🏽‍♀️ I just want a healthy pregnancy I should be happy not nervous
