First time TTC and cervical position??

My husband and I have been trying to conceive for about 5months now, but no luck. This is our 1st pregnancy after a miscarriage in April. Yesterday my cervical position was soft, high and closed (at 6dpo). Today it's firm, low and closed with occasional cramping on my right side and central lower abdominal area. With this change in my cervical position what are the chances were pregnant. A little worried that the change in my cervical position means we're not pregnant. Any thoughts please xx
