Anyone familiar with cervix checks??

Hey guys! New to the community and blessed there is so much support! TTC with my hubby of 7 years and so excited! Im on CD29 now and have been cramping since my positive OPK on CD17. Now the cramping has changed to period type cramps today with lotion (tmi) CM. Period is due in 3 days. Negative HPT and now my cervix is slightly open. Bad news??
