Hi everyone. I'm 36 years old and trying to conceive my 2nd rainbow baby after I lost my son at 21 weeks in early June. I am 8 DPO today and on CD 22. AF is due on Tuesday. AT 7 DPO, I felt a quick stabbing cramp on my right side twice (it only lasted a few seconds). Today I felt bloated and slightly crampy mainly on my right side. I was getting ready to take a shower and noticed this on my underwear. I wiped myself several times and did not see any blood. Could this be implantation bleeding?
