Ay, mama, that's definitely something you need to discuss with your OB directly kasi ang cervix thickness varies so much from person to person, and only your doctor can tell you if it's a concern for your situation! A few of us mums have had similar worries, pero lagi namang okay lang after proper check-up, sometimes it's just how our body is built, di ba? Definitely don't stress yourself pa, but do schedule with your OB soon para ma-assess niya properly and make sure everything's on track for your next pregnancy if that's what you're planning.
