For all those with yellow mucous, have your MW/OB check for group B strep. And, if it's positive, make sure they're giving you oral antibiotics throughout your pregnancy. I had gbs from 8 weeks on with ds that went untreated because my DRs said it was "common" and would be treated with IV antibiotics during labor... Well that's just not good enough. The infection got so bad that my water broke 5 weeks early. As a result, my ds spent a week in the NICU, had a spinal tap at 12 hrs old, and of course all of the other problems that come with being a premie. Most drs think it's no big deal but it is. I had a bad feeling and kept telling my dr and they said it was normal for someone with gbs to have the yellow mucous and it wasn't necessary to treat it until labor... L I A R S.... Ds was born with a fever and in critical condition because of the intense infection running rampant in his body. I don't want to see this happen to anyone else! If the infection is treated throughout pregnancy it will never be allowed to run rampant like that. I hope you ladies get it checked and that it's nothing. And if you still have the yellow cm I would have it re-checked every so often. You have to be your own advocate and drs don't seem to think gbs is a big deal. Btw, same thing happened to a friend of mine with the gbs, but her ds was born at 38 weeks and ended up in the NIcUfor a month because both lungs collapsed because of the infection and all the other problems he had... Only thing wrong was that she had gbs. Just saying, make sure you get it treated. It's not a big deal if you're proactive about it! Sorry if I scared anyone, just don't want you going through what I went through!
