You should go just to get checked. Not to scare you but I ended up having a hemorrage that early and now 23 weeks and fine.
I had this happen about 2 weeks ago. I called the ER room and the nurse told me not to go. But I was scared and went anyways. Midwife kept me for monitoring for about 4 1/2 hours because I had an infection from when your body is tired. Baby is okay but still scary. I'd go get checked just in case. :) everything is fine now.
I'd go to the hospital just in case. Or you can call your Dr and ask them what they suggest.
