Should I call midwife?

Yesterday I was ill. My morning sickness had gone but yesterday I started vomiting again and had diarrhoea. I went to sleep at bed time and woke up around 1am. Didnt go back to sleep until around 3.30am and all night I was having mild period cramps. I also kept feeling something trickling out down there. It's now 10.30am and I'm still getting it. Also woke up to a dried yellow coloured patch in my pants. A big patch asif i had peed a little, looked too much to be just discharge. When i leak and I put my finger there I can't tell if it's just watery discharge or if it could be amniotic fluid. I'm only 26 weeks so I'm worrying a lot. Should I put on a pad and see how it goes or call the midwife? I have been in a couple times because of other things and I don't want to go look like an hypochondriac 😑
