I need advice so two days before my cycle was supposed to come on I saw spotting very light pink so I thought my cycle was coming on which is normally super heavy and last 5-7 days . I had light pink and brown that didn't even really show up on my pad maybe a few drops of blood . This lasted for 3 days then it was just gone . I'm worried I was cramping just a little . Idk what's going on my cycle has never did that . It's irregular maybe off by one day but I always get a heavy cycle .I'm still having cramping throughout the day . Should I seek a doctor .
