Soft cervix @ 27 weeks

Throughout my pregnancy, I haven’t had any complications but the past few times DH and I have sex, I spot a little afterwards. After it happening again tonight, I decided to feel my cervix and it was hard to reach but VERY soft. I’ve read multiple things online saying it should still be hard or it’s normal for it to be soft but just looking for opinions! For about a week now, I have also felt inner muscular pain in my vagina as well as my tailbone hurting which I’ve read is from my pelvis spreading. Do I have anything to worry about?

I did have an ob appointment this morning and mentioned my spotting but my dr was not concerned.

Please help FTM out!!!! Thanks!
