You should get it checked out. I had very minor spotting at 32 weeks and admitted myself into hospital to find out that I was having contractions that I couldn’t feel. In the end was diagnosed with threatened preterm labour. Gynae gave me a jab to stop the contractions and luckily it worked and baby stayed in there till full term.
If its just a one time thing, can just monitor first see if it comes again. As long as baby is still moving well. I had a spotting 1 time in 2nd trim and panicked and went to a&e kkh, but all results were fine and baby still active.
