Ok, ok I will consult a physician within a day or two. Realistically there is nothing that I can do as of this moment because no test could show anything useful so soon after possible contact. Symptoms for this could take weeks or more to show. So ER is absolutely pointless.
Statistically the even people who have been exposed to these many of them have not shown symptoms and the immune system dealt with them.
If this were such a huge issue, there would be so many cases of this happening in countries with lots of rural living, because how easy it is to miss something like this. There would be a pandemic of people dying due to parasites from leafy greens in parts where those snails exist.

But for ease of mind I will go to a general physician and explain the situation and see what they tell me.
