See you doctor as soon as possible drink lot of water too dear best luck it seems like an infection avoid tight clothes and drink water as much as you can dear

You MUST make an URGENT appointment to see your doctor or gynaecologist if you are under his direction.
By what you describe, you do have an infection (which can happen with a cerclage) and this needs to be treated urgently.
Best wishes.
