Not sure what to think 😶

Jasmin
So I called my Drs office yesterday to see if I should be concerned that I lost my mucus plug and I was also having pinching stinging feeling in my vagina well the MA told me to come in today witch I did  well I showed her the picture of what I believed to be the mucus plug  she didn't  think it was cause it didn't have any blood in it ' but I read online that I doesn't always come with blood but after she  check my cervix  then she told me I am 1cm dilated and 75% thinned out  and that why thta stuff came out of me ( what I believed to be the mucus)  so I don't see why she said that wasn't my mucus plug ? 
But I'm not sure if I should be concerned or not ' I'm only 33 weeks and 5 days .....
This is what came out of meÂ
