Gas pain...

Can someone describe to me where and what they felt? 
I think this is what I experienced last night but am not sure.... 
I had pressure and pain in my lower abdomen, and into my groin area, which was a bit relieved when gas passed , but it was so difficult to pass it.... I was up most of the night with this uncomfortable pain... Debating whether to go to emerge or not...  I'm 16w today and I do think I had some ligament pain in there as well from changing positions and trying to get comfortable....
