Cervix positioning help!

Dana
Anyone have cervix remain slightly open 3dpo? Had positive opk and used trigger shot Sunday. Stopped BDing already (Tuesday night being the last time) now hoping I didn't O late. Normally I check my cervix throughout my cycle but miscarried in feb (at 5.5 weeks) and have been trying to be less intense about ttc so I stopped checking daily. Any ideas why it may be open still? TIA
