Does anyone experience bloating with Nexplanon?

I've had Nexplanon for about three weeks now. Last week, before I got my period, I started feeling like this heaviness in my stomach. I was very constipated so I just assumed it was that.

Now it's been almost a week since then and I'm still feeling very bloated when I eat. I've been able to pass bowel movements since then but still feel like my tummy is heavy. It's like my upper-middle abdomen.

I suffer from IBS and get bloated occasionally but not this bad I feel like.

I'm a little paranoid even though I haven't had sex since April. I'm going to my OBGYN on Thursday so I can talk to her about it but I'm wondering if anyone else has experienced this?
