Pregnant longer than expected?

Hi moms/mom-to-be,

I'm 29 weeks pregnant now.

My belly was high up before and has dropped quite a bit.

I'm also always running 2-3 weeks ahead of the pregnancy calendar in terms of how my body is developing/how I feel.

Throughout the whole pregnancy, I've felt like the baby would come earlier than September 16th. Like 3 weeks earlier, in the last week of August. This feeling is very strong.

I always had regular periods, but 3 weeks before I was supposed to get my period again, my body already felt different, but a test showed nothing. This changed when I went past my due date.

At 5 weeks, I couldn't even put on my own pants anymore.

At 10 weeks, we had an ultrasound and the baby was 3.5 cm.

We didn't do the 20-week scan. Medically it wasn't necessary, and we prefer to keep the baby a surprise. And any findings from an ultrasound wouldn't be a reason for us not to want the baby anyway. We've really thought this through carefully and discussed it with our midwife. We want to look forward to the moment in total relaxation, and if something does come up, we'll tackle it with both hands. Just briefly, why no 20-week scan.

Could I actually be 32 weeks pregnant instead of 29?

Anyone here with experience with this?

I have to go to the midwife again on Thursday and will mention it there. I'm really curious what she'll say.
