Ladies talk to me about cervix position

[happyface82]

So I had my embryo transfer 3 days ago. I’m inserting pessaries every morning and night. Last night my cervix felt so different. I wasn’t looking to see how it feels it just was so different I couldn’t help by notice. Everything seemed tighter, much tighter than before and lower? I’m useless and have no idea how it changes through the cycle - was wondering if it’s a sign. Any ideas?
