I started my period on the 6th (on time) is was very light spotting but the 7th is seemed like a normal flow, the 8th it was right back to a very light spotting again and now (the 9th) it's pretty much done...I didn't have to wear a tampon. It usually last 4-5 days with at least 3 days of medium flow. It was definitely an off cycle. Could there still be a possibility I conceived or has this happened to anyone before a bfp?... bfn?
