@Emz012019 I started an almost identical thread a week ago. I'm 30 weeks pregnant and last week developed 2. I'm assuming they're thrombosed, but haven't been examined. I've never known pain like it. I was crying and completely unable to do anything. I also had no constipation.
This is what I did:
I have a flexible ice pack. I spent hours sitting on it, or a bag of ice cubes. Make sure it's wrapped up so you don't get ice burns. This will reduce the pain and reduce the size. I wrapped it in a plastic bag and a cloth.
I bought germaloids at the pharmacy. It has lidocaine in it, which is an anesthetic. Or you can buy vagasil, which has stronger lidocaine.
I had taken paracetamol, which did nothing. I called the out of hours gp, who said I can buy over the counter cocodamol (be aware this contains paracetamol too, so don't take that and paracetamol). You might be able to take aspirin at your stage in pregnancy.
But speak to a doctor before taking cocodamol or aspirin.
Take a movicol sachet a day to keep your bowel movements soft, especially if you start taking cocodamol.
A few days after doing all this, they feel much better. I'm not needing pain killers.
Also buy a haemorrhoids cushion for more comfortable sitting.
The gp said they won't refer me for any further treatment for at least a month, as they may shrink down enough in that time.
