Missed 2 months checkup due to work

Hi momshies! My last checkup was September pa and it was supposed to be my lab test. When I got there saturday need pa ako i-schedule which I forgot na kailangan pala. So my schedule was on Monday, September pero may pasok ako at nagkanda-sunod sunod na ang field work ko. Now it’s November, next week palang ako pwede magpa-checkup kasi this month lang ako nagkaroon ng time. Question: would it be still okay for my OB to ask for an ultrasound before lab test kasi daming workloads sa office. Especially, I am the one who’s shouldering my bills & budget dahil yung ex-partner ko iniwan ako even if we have triplets. Thank you in advance to those who’ll answer :) #advicepls #pleasehelp
