Chemical pregnancy?

This might deserve a trigger warning and a little TMI warning too.

Ok so I got some weird (SUPER squinters) lines on a few tests early on, and a questionable blue dye (very faint, thought it was dye running or evap) and now af has arrived. Only it is very clotty and super heavy (I bled through a super tampon and a pad within an hour or so, then did it again in about the same time frame) Neither of which is at all normal for me. Cramps are terrible (which is normal for me the first few days)

Does this sound like a really bad period or a chemical pregnancy??
