Will a 4-day overstay stamp affect my entry into Thailand as a Singapore passport holder?

Thank you admins for the fast approval to this group.

Hi all, I would appreciate it if you have any advice/feedback or experience in regards to this matter.

I'm a Singapore passport holder (30 days visa free).

Back in late Jan when I was in Thailand, I had to take a 48hrs pre departure PCR test back to my country which ended up having some issues and had to redo a new test.

It was the weekend and I wasn't able to go to the immigration office to extend my visa and ended up overstaying for 4 days. (Before anyone says serves you right, yes I admit it's my fault and I paid the 2,000 baht fine and had an overstay stamp of 4 days at BKK airport). No blacklist was given to me.

Long story short, I'm planning to visit Thailand again at this end of the month for 15 days this time (obviously scared of making the same mistake again). Already did my Thai pass and pending approval. Will the overstay stamp of 4 days affect me entering the kingdom or will I be denied entry at the immigration at BKK airport upon arrival?

Thank you in advance!
