AF & Cervix - warning TMI

[~Debbie~]

Yippee for me, AF has returned... ttc#2 coming up

On the first day of spotting, i felt my cervix, and it was quite high, tip of my finger, but, today, AF very heavy, and i tried to use a tampon, but, felt it being rejected, or some ressistance. So, i felt again, and my cervix was very low.

Is this normal? And, can i still use a tampon?

These are terribly embarassing things to have to ask..
