Contractions waking me up

So I’m 38 weeks exactly and I’ve been having on and off pains for days but over the last 24h they have been getting slightly more regular. I lost my mucus plug about a week ago and had a bloody show yesterday morning. It’s now 2:38am and I’ve been awake since around 1:30am with what I’m sure are definitely contractions. The pains woke me up from a pretty deep sleep too🫠 My question is, I’m due to go in for a c-section in a week. Should I be speaking to mat assessment just now? I definitely do not want to try for natural labour due to previous birth trauma (this is my second) but I also don’t want to phone them and they tell me to go away and stop being dramatic😂 I’ve not timed any yet so I’m definitely going to do that too
