Hi,
I have had the exact same pains and recently posted about these, the pains I had were sharp stabbing pains that took my breathe away down both my right and left side of my abdomom. I looked them up and found it to be round ligament pains so dont worry about it!!
Also i was getting the pains down below and still do now but i have had a scan and everything is fine so dont worry about them, it is just your body responding to being pregnant!!
