Miscarriage or period?

My period is extremely irregular. I had a one day, super light period on Friday, 4/20. I didn’t even wear a panty liner or anything it was so light. My husband and I had sex 4/21, he ejaculated inside me. I have been assuming there is no way I’d be pregnant with me just having some type of period the day before and bc of the irregularity of my cycle. One week later, Friday, 4/27, I go to an amusement park and ride 2 roller coasters. The next day , Saturday 4/28, I have large amounts of clear mucus and am spotting again. No cramping or anything, but I instantly freak out. Also, hubs and I have not had unprotected sex in a while, conceiving is not what we want right now. We just got a little cray. 😂

Do you guys think I would’ve been pregnant and now miscarrying?

I know I can’t get an official answer from anyone here, but has anyone experienced anything similar?

Should I go take a test even with it being so “early”?
