My daughter is really low.

I’m 16 weeks and 3 days and my baby feel like she is sitting super low I have a ton of pressure down there and sometimes I can’t even sit in a upright position because of how low she is. I’ve never had this problem when I was pregnant with my son he’s was always super high up my whole pregnancy. Could this be bad that she is so low?? I get sharp shooting pains in my vagina as well. Could her being so low cause me to have her early a lot of people say second babies come earlier then first babies.
