The past two months my period has only been 4 days of brown blood only. no red at all. my periods are normally on time and red. could i be pregnant?

Maybe: If it arrives a bit earlier, is lighter than normal, and has more of a brown color than red, you may be experiencing implantation bleeding which occurs 10 - 14 days after ovulation and indicates that the fertilized embryo is pushing into the uterine tissue, pinkish brown bleeding/ spotting results it could also be you many have had an anovulatory cycle (no eggs released). If neg. Pg test, see dr.
