I need opinions who ever experienced IPB (implantionation bleeding) I have never had it or never really payed it any attention. So my period is light the first day but then gets heavy the second day with really bad cramps and its messy body sore etc third day its slowly gets lighter fourth day its extremely light and gone by fifth day. Now I been tracking my ovulation so I wouldn't get preggo buuut I messed up and forgot my days and had sex on them. My period isn't due til 11-10 I got dark brown bleeding 11-5 and my ovulation days were October 18th - 24th period october 10th - 14th this tracker says the same as my <a href="https://play.google.com/store/apps/details?id=com.glow.android">glow app</a>. COULD THIS BE IPB ? now with this bleeding its so light no cramps and no bright red like a period but does have a bit of a period smell. My photos are in comments.
