Chemical pregnancy in beginning of January.. then regular period. Now period due in 3 days. Been spotting light on and off for 5 days. Changing from light pink, brown, milky discharge mixed in.. Haven't taken a test yet. No signs of period. Not even enough to to barely get on toilet paper. Some cramps here and there even. Should I be worried? If it's implantation bleeding I haven't heard of it this long except for twins. Lol
