Bloated after eating and taking tests

[bigtime]

I am often bloated after eating and was thinking I might have food intolerances. I was thinking of taking a test from this website and wondered if anyone has with decent results or is it a con? https://ukfoodintolerance.co.uk/?_gl=1%2A1969s97%2...

I’ve tried the food diary but bloating and constipation flares up and there seems no pattern so was hoping to purchase a test.
