39 weeks pregnant with std 😓

I’m literally heart broken, I’m 39 weeks pregnant and I get a call from my doctor saying I have trichomoniasis, bacterial vaginosis, and a yeast infection. I’m so hurt about it bc I’ve been with my husband for 3 years and he’s the only man I’ve ever been with and I just got all of this at once so I know he cheated on me and I’m so scared that if I don’t finish my antibiotics on time before the baby comes I will have to have a c section 😓 I’m not looking for a answer to anything or even a reply just needed to vent .. 😩 I just hope my baby girl waits to come until everything is cleared up ..
