I've never had heavy periods, I usually have a day or 2 of a moderate to heavy flow, then heavy spotting/light flow for about 3 more days. My question would be, since my periods are normally on the lighter side, would I likely mistake implantation bleeding for a normal period? I got my normal period 6 days after intercourse (2-4 days early), it lasted the usual 5 days, was red and had some clots. Would implantation be like this or is it really just an early period? I was early last month also. I do plan on testing, but it is still too early.
