Okay i need your thoughts, so I was supposed to get my period on the 20th and I started to lightly bleed on the 17th when I wiped so I dismissed pregnancy idea and put a tampon in. Its been super light (not enough to fill tampons) but the blood is bright pink almost red but never enough to fill a tampon and I change them every 3-4 hours. Like a quarter of the way sometimes less on tampon of color. I cramped the first day on the 17th but no cramping really on the 18th. And at night I barely bleed at all. I'm starting to wonder if it's Implanation bleeding vs Aunt Flow. I'm typically always on time and my periods last about 6 days tops. There was a little mucus mixed in one of tampons with brown as well. I'm so confused. I've been having pregnancy symptoms leading up this. Nasuea, food adversions, throwing up, bad lower back ache and tired, and bad headaches for about a week now. Any thoughts ?And when should I retest for pregnancy? or do you think it's period?
