Unsure Due Date

Gabrielle • She/her

Is anyone else like me and are incredibly unsure of your due date? I haven’t had a period since November and was kinda shocked the end of my stint without one this time ended in a pregnancy! My blood test said I was anywhere from 6-8 weeks! I have an appointment next Monday, but has anyone else experienced this? It makes me feel weird, like everyone else seems to know exactly how far along they are but I don’t.

Edit: my issue is irregular cycles, which are new for me.
