Really need feedback.

I got a positive pregnancy test and went for a blood test. My HCG level was low (16) so have to go for another one in 2 days.

However, for the last 4 days, for about 1 hour nearly the same time I get a little light brown discharge that’s quite creamy. What could that be? I technically would be due for my periods in 5 days.

Last month I started getting red spotting, and got a positive (faint line) pregnancy test but got my periods so possible a chemical pregnancy :(

I’m just really scared it’s going to happen again.

Is this normal and has the brown discharge happened for you? If so, how long did you have it?
