My cycle before TTC was pretty much clockwork 27 days. I am just starting cycle #4 TTC and have so far had cycles 24, 26, 24 days. I know it's only a few days but have never had this before or a cycle as short as 24 days. The supplements I am taking I started 3 months before TTC so I cannot be them. Is there anything do to with TTC that would cause cycles to get shorter? Thanks
