Nervous FTM-Braxton hicks?

So tonight after my husband got home from work, I got dressed and ran down the road to the store. I then got what I needed came home and started getting dinner ready. I started to get this extremely bad pressure in my pelvis. I know it's pretty much normal to have pelvic pain but this pain was extreme! I then started to get nauseous, so I sat down for a bit and now I believe I'm having Braxton hicks. They are uncomfortable, but not as bad as the pressure in my pubic bone. My belly gets hard for about 25ish seconds and I've had about 5 of them with about 3mins inbetween. I also think they are easing up. FTM Linda freaked out..
