Difficult to know what to say. You might have reacted badly to early season losses and changed too much at one time or you might not have. Can't really tell from your post how long you stuck with what worked before or when you started to changge things a lot.

The most important thing when making changes is to be able to see what works. If you change players, formations, orders or whatever at the same time then it becomes difficult. An unexplainable dip in form followed by the wrong changes can turn into a major slump.

You need to decide what your new target is for the season and then judge if you can reasonably expect to get the minimum you'd expect. (I've no idea what 9th is relative to top or 2nd or 4th or 7th.)

If it was me I'd try to steady the ship. Instead of looking to beat the next opponent I'd look for a balanced formation that utilises my best players and minimises my weaknesses. I'd even consider taking a counter-attacking only outlook for a few games just to see what happens but I'd do that based on being able to see all the matches and opponents and making a judgement.
