Spotting TWICE? Has anyone else experienced this ??

I had my last period January 25 - Jan 30 and started spotting for a few hours on 02/12. The color started as a light pink gooey discharge and became a rustic brown color. I thought maybe my period was abnormally early but nothing else came of it and I didn’t need a liner or pad because it was so minuscule (mostly only noticeable when wiping). Anyways, that completely cleared up within a few hours .. and I’m expecting my period to be on 02/20-02/21; but I just started spotting light brown again. Which seems normal sometimes before my period but ... I had to use a tampon to find it. I wiped once and saw it and then it completely disappeared. I used a tampon to see if there was any blood up there and that’s the only way I’m able to see the brown spotting as of now. I’ve been waiting for the past 12+ hours or so thinking that AF will pay a visit but I’m not so sure now..

Is this normal? Any advice?

Has anyone else experienced this, and if so what was the outcome?

Is it worth it to take a pregnancy test or ? Do people spot twice in pregnancy? I’m very confused

My cycle is generally 25-26 days long on average, my boyfriend and I have been using the withdrawal method instead of the usual condoms. I’m not on any form of birth control either.
