Should I go to Maternity triage?

It's 1am in the U.K. now so don't want to wake my other half up when he has to be up for work... all day I have had stomach cramps, like period pains I guess across my stomach, I've felt nauseous all day and as a result haven't eaten or drank anything all day bar 1 bottle of water. I've just been lay on the sofa with the sudden urge to be sick and have been sick throwing up possible stomach lining (what else could it be I haven't ate!?) for ten minutes straight my stomach is in agony! Do I call triage and wake my partner or could I just be sick off food from the previous days tea and wait until the morning? 😔
