CM question....

Desiree

So it’s been almost 1 yr since my miscarriage and its like I feel like I might be pregnant but I have irregular periods but I always get one and my last one was March 20 something and so by Glow Im going on 12 days late and I took a pregnancy test Saturday morning and it was negative and I haven’t had many symptoms either, only feeling tired, back pain and my GERD is worse and going pee more but idk if its because my mind wants me to be or if there’s still that chance.. anyway this morning my CM was like watery/egg whites not sure if that means anything but wanted to ask you guys for opinions... how is CM if pregnancy happens?!?
