Is it normal to not feel pregnant anymore?

Hey, I should be 11w3d according to ovulation and the first two ultrasounds at 6w1d and 8w2d. Everything was fine and on track then. Last week (10w4d) I went to my doctor because I had brownish blood/discharge. She cjecjed and everything looked fine, baby was moving and had a strong heartbeat. But it measured even ahead 11w2d.

But I didn't change my counting, I wanted to wait until my dating scan next week. So, instead of going by the last appointment where I now would be 12w1d I think, I'm still thinking I'm 11w3d.

But for the past 2-3 days I just don't feel as pregnant anymore. Never have had much symptoms. Just tender boobs (that don't really hurt anymore) and occasional cramping or round ligament pain. But for the past 2 days... Nothing...

Should I be worried? Or is it just because I'm ending the first trimester?
