Im late ..

I apologise in advance if this is not the proper group to post this but I'm new here and this is my first post so bare with me. I've had the implant nexplanon for 3 years. It got removed in July and I've been trying to get pregnant since Oct. When I was on bc my period was every other month but as soon as I got it took out, it went right back to normal. Except now ,I was due for my period on Jan 31 and still have not got it. Any thoughts?
