I had cramping and bleeding until 5 weeks. I had so much bleeding I needed a tampon. Everything went away when I turned 5 weeks. I hear cramping is normal as long as you don't have a ton of bleeding. Your baby is just burrowing in and getting comfy for the stay!
As for my bleeding, my doctor did an ultrasound, and although he couldn't see much, he said everything was fine since my HCG levels were rising as they should be.
i had bad cramps up until about 5 weeks. I think it's the implantation stage. No doubt it'll ease up soon. I'm a first timer also.
