Soft cervix 12 weeks

Em

I’m almost 12 weeks, I’m not checking it intentionally but I do vaginal progesterone so I do feel it when inserting (hands are always clean and I’m simply doing my meds) but my cervix feels really soft and long.. I thought jt was supposed to be firm? Should I be concerned? It’s felt this way for a while but I do have a history of preterm birth with my first so I’m paranoid with this pregnancy.
