How common is implantation bleeding really? I did not have it at all with my first pregnancy nor did I have it with the pregnancy before that unfortunately ended in a miscarriage. I have had some dull cramping since yesterday; can be described as a heavy feeling, and just had some pink/brownish spotting on the toilet paper, very minimal. I still have that heavy bloated dull crampy feeling. Definitely don’t want to get my hopes up that this was implantation bleeding, but my period has never come sooner than probably 13 dpo so I can’t imagine it’s coming now at 8dpo. Any insight?!?!
