I finished my period about 5 days ago, straight after my period I was taking the pill for two days and then I just stopped taking them all together. During these 5 days I have had intercourse with my partner quite a bit. Today is the 5th day or so and I just got home went to the toilet wiped and then realized that I was bleeding again. The blood was not too heavy but definitely not light. Could this be implantation bleeding or could this be from the pill?
