So my period have been weird since I’ve been on my new Pill BC (put on them in October) this month I forgot my last pill so I took it the next day, my period usually starts Wednesday but this month it started Thursday, it was lighter than usual, but I had all my regular symptoms(over emotional the first two days, headaches, gas and extra bowel movements) this picture is from the last day of my period, and I remember my boyfriend and I were sexually active the week or two leading up to my period. Could this be implantation bleeding or just a light period? ( the light, red, clot bleeding lasted 4 days)
