Cervical position

Rebecca • May 30th 2013 received my first son! ttc baby #2 since September 2014.
7 dpo, usually my cervix is reachable at this point in my cycle ir kinda low, checked it today and it's so high up I can barley touch it! Never had it be so high before and it's very soft! Had cramping like serious cramping at 5 dpo, anyone else go through this a get there bfp! Also if I implanted at 5 dpo how soon can I take a test?
