1St and 2ND trimester

So I'm going on 13 weeks Tuesday getting out of the first trimester which is awesome cause I had almost all the symptoms, but now it's fear almost cause I'm not really experiencing anything I guess. When I woke up this morning I had wired feeling like I don't feel pregnant anymore, now I know it just a fear probably since last Tuesday heartbeat was 150 and no blood. Anyways has anyone else felt like this at all or close?

Maybe I just haven't gotten used to being pregnant. Do you ever?
