Has anyone had a late period because they took prednisolone acetate eye drops? I know prednisone pills can cause issues, but I'm trying to figure out if the eye drops in particular can screw things up so bad. I'm a week late. My BBT has been all over the place this month, and Glow says I ovulated on CD23. I quit paying for OPKs after I didn't get a read, so Glow's calc is based on my BBT (and maybe symptoms?). I'm now on CD 35. No BFP. I've been regular since June. MC February 2014.
