What is going on??

Okay, last month I had my period on September 7th. I ovulated Sept. 21st. I had bleeding September 30th. ,Extremely light for only 2hours.

Oct. 1 @ exactly 4:21p.m. I went to the bathroom and I was bleeding. I'm having cramping in my lower stomach and cramping in my lower back. Its heavy. Not really any clots though.... I'm not suppose to start my period until the 6th of October. Its now 4:55 a.m. on October 2nd. And I'm still bleeding heavy but what's weird is this whole time its only there when I wipe, not any on Pad.

According to my other App September 30th was my implantation day.

Any suggestions???

Is my period really early or what going on?

Anyone ever experience this? Thank you!
