Help!!!

Melanie

I am so confused right now. AF was due October 15th, but instead showed up October 16th to trick me. But on that day all I had was spotting not enough for a pad or tampon. Then the 17th only blood when I wiped nothing on pad. 18th, same thing, 19tb just a tad bit of brown stuff. Then gone. Now I’m having pinching on my left and right side. I’ve done hpt’s and still negative. I’m so confused. I can’t tell whether I had a late ovulation and I just went through implantation bleeding and it’s too early for it to show on hpt or if I just had an extremely light period. WHAT IS HAPPENING WITH MY BODY!!!!!! Any advice or help is greatly appreciated!!!!
