Pregnantttt !!?

So today I received my very first positive test after ttc for almost 18 months! Baby #1 for me and my Significant Other. I do plan on testing tomorrow morning because I’m scared it’s wrong 😭. And if I am pregnant I do not know an estimated due date since I am VERY irregular I can go from having a period in 2 months to 7 months 🤦🏽‍♀️ BUT if I go off my last period I would be 11 weeks which seems too far along but we’ll see tomorrow after I take a test I’ll a schedule an appointment with my dr. ❤️ I pray this is a true positive for us 🙏🏼
