39+4 and struggling with a migraine

I went to get the baby checked last night as I had felt there was a reduction in movement and I was suffering an awful migraine. Luckily all checked out ok. But I still have my migraine! I’m really struggling today. I managed about 3 hours sleep and that was only when I slept with a cold flannel on my head. Any tips? paracetamol, caffeine, etc are not shifting it and I’m at my wits end. My left eye is pulsating and tablets give me about 30 mins relief only
