@monkey88 i hope your appointment goes well and they are able to give you some answers today! Fingers crossed everything is going to be ok.
Also regarding cm i never go in and try get some haha, only go by whats on my undies or when i wipe. You will have watery cm leading up to your fertile period and then you will start getting ewcm a few days before you are due to o. You should be able to notice it when you wipe as it will be shiny and stringy like egg whites. Just remember not everyone ovulated around cd14. I was often ovulating cd18, so its best to use opks and keep an eye on the cm to know when you are about to ovulate. Once you have ovulated your cm will go creamy
