Okay, so on the 21st (Friday) I went to the bathroom and noticed some very light spotting. I got kind of excited because I have never spotted before any of my periods in the past, so I thought maybe this could be implantation bleeding. This was day 22 of my cycle and the bleeding only lasted that day and there wasn't very much. AF is expected on the 27th, and like I said, I haven't bled any more since Friday. I'm racking my brain over this, because I haven't experienced any other symptoms (other than some light cramping). So basically, I'm just wanting your all's opinion on this so I can stop over analyzing it. Is it implantation bleeding, or something else? Thanks in advance!
