Relationship help, PLEASE!

Ashley
Found out we were pregnant at 4 weeks and couldn't be happier with our rainbow first baby❤️ go in for first appointment at 10+4 weeks and also get my first pap done (I'm a young mommy to be). That Monday, nurse calls me and says I have an STD. Of course hubby and I are both shocked, take antibiotics, and start the blame game, swearing up and down it wasn't  me.. Between Monday and Wednesday he declares he doesn't want to be married anymore because he doesn't know what to believe. Come Wednesday afternoon, we sign up for counseling because he only wants to communicate with me when it has to do with the baby. Right as we walk out of the office the nurse calls and says sorry for the confusion and the mistake but your pap only came back with a UTI, not an STD. To my relief I'm joyous thinking my marriage will go back to normal, however we are not back on good terms at all and haven't said more than twenty words to each others face all week. Sorry for the rant just need a little guidance.. I'm absolutely beside myself and the stress is causing me to have the chills, fevers and headaches..
