Hi Eva,
I am about 6-7 weeks pregnant and I have aches and cramps in my womb/ovary area, a bit like period pain, nearly all the time. I haven't been to the doctors about it but I've read it's quite normal, and it is also normal to experience gas and heartburn and bloating in your first trimester.
Try not to worry and book an appointment with your doctor if the pain is persistent.
