A symptom of PCOS is severe pelvic pain actually, often due to issues with the ovaries, so more chance of cysts and even without that severe pain during periods and severe pelvic pain outside of periods as well are PCOS symptoms and very common, just not one used for the main diagnosis. Also, adenomyosis and PCOS are commonly together, just because she may have one doenst exclude the other.
Also, I understand tranexamic acid wasn't useful for you, but it is for many people. Maybe you should have had a higher dose, or maybe it just wasn't for you. That doesn't mean OP shouldn't at least try it. It works amazingly for many people, I have a good dose, which has always worked amazingly despite bleeding very heavily and through 7 layers.
Your one experience doesn't mean a drug is bad or doesn't work because you don't have controlled data and you are 1 person compared to many. I'm not saying you aren't right. You are right about your own individual experience, but when we have science and clinical trials, we use masses of data and more than one person's experience.
Medications go through so many stages and are tested on thousands of people to get on the market they have to show 1. It works and is safe, and 2. Clinical significance, which is for medicine. It means the drug not only works but works significantly enough to make a difference
For example, let's say a new blood pressure med is developed. They show it works and reduce it by 1-3 mm. It's also the cheapest of any of the blood pressure meds.
It will still be rejected. Why? Because 1-3 mm for blood pressure meds is nothing, it is not clinically significant and so is pretty useless when we have ones which reduce it my 10 mm points. Even though they may be more expensive, they work better, and so stop people getting worse and needing more intervention, and getting sicker and costing more.
The cyst has likely gone @MyPinkTraybake. It was likely a simple cyst that is normal, and everyone produces each month - that's the cyst to ovulate an egg, so those are normal and a good thing.
If there isn't much pain, that's good. It means you don't really need to try NSAIDs or higher pain meds. If it's a little worse, use paracetamol or ibuprofen. Would you be open to trying the mirena coil? The bleeding doesn't sound heavy, but it would still reduce it by thinning the uterus lining and getting fewer blood vessels there so there's both less bleeding and fewer cramps. For the insertion, you take paracetamol and ibuprofen 1h before, get licodaine injected into the cervix and numbing gel or spray as well.
Or for now try tranexamic acid and if that doesn't work northisterone. Again, start using it 3/4 days before your period starts. Ask your GP at the appointment after you get the bloods back.
On the naproxen, I would get something else if it's only headaches that are the issue, it does help with headaches but there are other meds you could use as specific to them? It depends, what type of headaches are you having? There are drugs specific to migraines - like triptans, I would bring it up to your GP and try triptans, perhaps, as they are 1st line for that.
Have the bloods come back yet? If it is a full blood panel, TSH and thryoid will be included in that. Give us an update when they do, and whatever they say, go back to your GP. At the very least, get the hormones tested again and also another transvaginal ultrasound.
Good, they are checking the folate. If it's low, then get on folic acid as well again. If the iron is low, again start iron pills but get them prescribed so that it's a higher dose.
Do you think PCOS could be the issue? I mean, if they don't see the follicles, then rule that symptom out but get another transvaginal and see what they say. If you have irregular periods and also some hormones at specific levels (both some high and others low), you'd qualify for the diagnosis.
