A cousin mentioning something and a bunch of inductive DYOR googling are both far weaker than the data provided. The main pressure on doctors is to remain scientific, which is currently incompatible with claims linking clots to the rigorously tested, surveilled, and proven vaccine. There is also a hard bias against doctors saying that spiritual possession causes epilepsy or that smoking is secretly healthy —and I’m glad.

The CDC continuously updates its surveillance of the vaccine via VAERS. Via VAERS, if any of those early warning signals reached significant levels, they would follow up with deeper studies. To date, that is not the case.

There are many questions worth asking yourself before you attribute your health issue to a vaccine:

Did I ever get COVID-19?

The risk of blood clots increases for at least 6 months after the virus.

Regardless of current fitness, have I ever had years of sedentary employment?

A computer heavy job (for instance coding) or lifestyle (say, one where you write long replies online or play videogames often) can be a major cause of cardiovascular issues for years.

Will another answer than the one you’re searching for satisfy you? Or is this truly a search for confirmation?

Nobody is saying that a link between your clots and the vaccine is impossible. They are gently reminding you that a massive body of evidence suggests it is as likely as a forest fire being caused by rain.
