Not my typical cycle. Any advice would be appreciated

Ashley
I have been TTC for a few months now. This month my husband and I have been trying the SMEP and BDing every other day. I am on cycle day 22 and all of my Cycles are around 43 days. For the past two days I am bleeding. It is Red and similar to my period in the amount but I am not having menstraul cramping. I am having some stabbing pain near my right ovary. I am also dizzy and having waves of being nauseous. I take OPKs daily and I have not seen a peak but instead high estrogen on the tests which is how I have been each cycle. Anyone have any idea what the bleeding is? Could it be implantation even though it is a lot and red? Is it an early miscarriage?
