First scan


So based on my last period, the midwives estimated me to be 8 weeks but I'm pretty sure we conceived at the end of December (when we actually tried!). My periods have always been irregular. I have my first scan February 7th but I'm afraid it might be too early to see anything if my estimation is correct. I don't want to be let down or have to come back a week later, BUT I'm dying to see what's inside of me. Anyone else in a similar situation? What do y'all recommend?
