Are all my symptoms pointing towards endometriosis?

So I wondered if anyone could help me with my symptoms if anyone has had anything like this or what it could be etc etc...

I’ve always had really painful periods but last week when it started I was in complete agony! I couldn’t even walk properly. Painkillers wasn’t helping.

My periods are always regular and have never caused any issues apart from the monthly pain.

My boyfriend and I have been trying on and off for a baby for 3 years. (We did a home kit to test his sperm and it came back fine). We also got pregnant before, 4 years ago but unfortunately I had a miscarriage.

I’m now having constant period pains but they are very light and the pain is not bothering me, just worrying me.

I’m 22 so haven’t had a smear test.

My doctor has suggested to have an ultrasound so I might be able to go for one this week.

Does anyone know what I could be looking at here? I keep googling and endometriosis keeps coming to mind.

Any thoughts and info would be much appreciated!!
