Weekly Dr. Appointments?

FTM here, I start my weekly appointments this week (I'm 36 weeks) & I think my next appointment my doctors going to take a swab sample from my vagina to test for stds & everything else.. & I was just wondering does the doctor use the speculum to do this? And will she use the speculum every weekly appointment? I really hate that & it makes me want to cry it hurts soo bad. I'm stressing about this so anyone who can answer my question please help. Thank you.
