Hi everyone, I think I've just had a chemical pregnancy. I started bleeding lightly on Wednesday, CD21 and thought it might be implantation bleeding. My cycles are normally 31-33 days. I had bleeding that was light for AF but heavy for spotting, so I did a FRER and had a second line. Then I started bleeding more, which now, 5 days on, is very much like AF. No line anymore 
does this sound like a chemical?
