I have a couple questions?

Cierra
What does your cervix feel like before AF? Mine usaly drops the day expected witch was yesterday and I couldn't find it all and today I could feel it but its way up in there shouldn't it have lowered if I was going to start my period? And I'm having a medium amount of creamy cm it varys depending on the time of the day. My boobs are more sore then normal and have bumps around the nipple that are a bit larger then yesterday and there's more of them is that normal? I'm bloated like always but no cramping witch I usaly cramp really bad thru the whole cycle? I'm two days late and I don't think AF is coming I could still be wrong my cycle is 28-31 days long I'm on day 30 now should I test or wait? What is my chances on actually being pregnant with all of this information?
