I am not sure if what I experienced was implantation bleeding. I was supposed to start on the 24th this month but on the 19th I had a gush of blood which I thought was my period. I had been sexually active on the 31st of January by the way. Anyway, after that gush my bleeding began to slow down A LOT. It was sort of a pinkish, bright red kind of color and I was either spotting and or lightly bleeding for the next few days. I had what looked like a brown discharged that I seen whenever I wiped. I thought if it was implantation it should stop within a day or so. But the spotting last for 5 days. The cramps I had during that bleeding wasnt as near as bad as my usual cramps. My boobs are VERY sore and sensitive and I have been getting nauseous a lot lately. I am not quite sure if I am pregnant due to how long the bleeding lasted and the initial burst of blood at the beginning. But it did indeed look a lot like implantation and had a brown discharge. It did not seem like my normal period at all, especially when I was seeing about 3 little spots of blood on my pad on day 3. What would you expect is going on?
