If cervix is real low is it a sign of early pregnancy ?

Me and my fiancé have been tryin to conceive my last menstrel cycle was 4 days late and my boobs were bigger and sore and stopped after starting my period now my boobs are gettin bigger heavier and sore again and I just ended my ovulation window my lower back has also been hurting sleep patterns off and when we were fixin to start some foreplay he felt my cervix just by a finger length in so I'm just wondering ...
