All advice welcome!!

I’m booked in to see an obstetrician on Thursday. I will be 21+2 Weeks And no one will tell me why. I’ve read up on reasons why I could be seeing one. Do you think it could be because I mentioned my other half’s dad supposedly has schizophrenia?? I told them there is no proof as it’s just what his mum says... or maybe something to do with my last pregnancy/labour as I had a failed vontoos and ended up having forceps??

Would love a rough idea before getting. Into the room as I am bricking it and as no one will tell me why I’m going to see them I get more worried as the day gets closer xx
