Insurance question...

So my husband and I haven’t met our deductible yet & the last time we payed a bill was in November.... we’ve called our OB office and they said everything is up to date and we don’t have a payment due or anything, yet I’ve still been going to my appointments regularly. Plus I went to L&D end of January for monitoring & we haven’t gotten any type of summary or bill.

I’m a little nervous because I don’t want to get bombarded with bills, has this happened to anyone before?
