Crying over nothing 6dpp

I'm 6 dpp and I cry over the stupidest things. Like I'm not pregnant anymore, I miss my bump, the kicking. I have a beautiful baby boy but just someone saying or even doing something nice I start crying. It took us 5 years to Concieve him and I'm terrified something bad will happen to him I look at him and feel so much love. I had the mirena coil fitted during my c- section I don't know if it's normal hormonal pp mixed with that but I can't stop crying unnecessarily and worrying that something bad will happen to my baby.
