Pains??

So I'm 27w6d and so far in my pregnancy I've had none complications, so yesterday I started having pressure in my lower abdomen along with sharp pains and stabbing feelings in my vagina every now and then which stops me in my tracks at the time but nothing that concerned me too much, however I woke up during the night with bad lower back pain and a bit of pressure in my lower abdomen but I thought I'd go back to sleep and see how I was when I woke up, so I've woke up this morning and I'm still having pressure every now and then and the sharp pains also accompanied by lower back pain, I'm just wondering if anyone else has had this and it's been nothing to worry about its just typical pregnancy pains(however I never had this with my first) or if I should be concerned even though my pregnancy has been healthy so far? Thanks mamas
