What is the right week to track?

I am 7 weeks pregnant according to my LMP. I had a dating ultrasound done and they told me gestational sac and yolk sac all looked good, couldn't find a baby yet though because I am only measuring at 5 weeks (they reassured me it's just because it's too small right now.) This all makes sense due to #1 having sex about 5 weeks ago and #2 my ovulation cycle that is normally about two weeks after my menstrual cycle. I am trying to figure out though, on the bump app is our baby an Appleseed or a blue berry? Which am I supposed to follow/track here 🤔 Since I found out I was pregnant, baby would have been 2.5 weeks (about 5 days late on my period). I had four very quickly at home positive pregnancy tests. If I am following 5 weeks on here, it's saying at 2.5 weeks baby didn't exist yet... So lone behold I am really confused 🙄
P.s. First pregnancy here, so this is all new to me still 😁

It’s based off the start of your last menstrual cycle. They will give you a better date when they can see baby to measure.

You base the weeks off your lmp, the first two weeks of pregnancy are freebies because your not even pregnant yet. It’s normal to measure behind a little, most babies catch up. They’ll likely have you in for another scan. Also if you’re not tracking ovulation, that could have been off as well.
