More than likely it is your door seals and the water is taking the path of least resistance, you should also check the windshield area for leaks.
It should connect at the back of the sunroof under the headliner and I think the hose drains out of the trunk near the rear wheel well.
There is a drain tube that goes through the firewall and comes out under the car. Use a piece of wire to stick up there and unclog it, water will run out when you have got it.
Consider mold growing in the jute (soft padding under the carpet) after exposure to water. Also check for water leaks at windows (including windshield) around doors or in the trunk.

What water are you talking about? Water under the sink, yes! Water because you're pregnant, no!
It leaks from the failed part.
Water can accumulate under the rear nearside carpet of an Astra G due to several factors, such as a faulty door seal, a blocked drainage channel, or a leaking window. Poorly sealed or damaged weatherstripping can allow rainwater to seep in, while clogged drainage systems can cause water to back up and seep into the interior. Additionally, condensation from the vehicle's air conditioning system or spills can contribute to moisture accumulation. Regular checks for leaks and proper maintenance can help prevent this issue.
The most prosaic explanation is that something spilled there and the water soaked through the carpet.
