So I was suppose to have my period on the 4th to the 7th but on the 4th of this month I got a really rough cramp pain and came out I did not had my period, so on the 8th to 11th I have spotting which was pink 2 days and then a little light red spotting, then brown and then pink again. But no heavy flow and it already stop today, can it be implantation bleeding? I was like that with my first daughter and the same pain as my second child, I keep with negatives but I feel on my heart something that tells me I am pregnant..... how many days do I should wait to test again???
