Can having down a lot of pelvic exams cause a miscarriage?

Gabriela • First time mom. 23. Due 06.26.17
I am currently 5 weeks and have had 3 pelvic exams including one early ultrasound. Everything has come out normal, but I'm just very worried. Iv had STD testing, vaginal culiture, and yeast infection culture. I went to two different doctors at the same office. I know I went too much, but I was just worried and wanted to make sure everything was fine.
Please advise ☹️☹️☹️
