Late period

Today’s marks day 3 of my period being late and I’m scared to take a pregnancy test 🤦🏽‍♀️. Before anyone ask, Yes! I do want to be pregnant and No! I don’t have an irregular period nor is it normal for it to be late like this. I just don’t think that I’m ready, hell or even stable enough to become a mother 😩. How do you prepare yourself for this great moment in life? Just in case I am pregnant ..
