Still haven’t had it

You almost certainly have. A substantial minority never develop symptoms. It's one of the things that makes it spread so easily. If it made everyone very sick they'd all be safely tucked up in bed and not spreading it.

There is no useful answer to your question. Some people develop symptoms very quickly, some people are asymptomatic for a period, others remain asymptomatic throughout.

If you think you've been exposed and you could put others at risk, do a test. False positives are common but they're better at picking up people who are very infectious so that's something.

If you want to know if you've had it, there are antibody tests which check for antibodies from infection rather than vaccination. (Example for information, not a personal recommendation.) They're not 100% accurate but a positive is most likely a true positive, given that the vast majority of people have had it by now. They test for two types of antibody, IgM and IgG. IgM should only show up during or immediately after recovery from an infection, IgG turns up later in the course of an infection and sticks around after recovery.
