Hi czreader, what you are experiencing with reduced bowel movements and gas is not at all abnormal, that's one of the main reasons why enemas are recommended while fasting.
How much water were you able to take using the bulb syringe? You need at least a quart, preferably 1 1/2 to 2 quarts at least once a day. In your situation you may want to have an enema first thing in the morning or around mid-day and another at bedtime.
When self-administering an enema with a bulb syringe it difficult to get much more than half the capacity introduced with each squeeze. Typically, with an 8 oz bulb you can expect 5 or perhaps 6 ounces per squeeze. So if you wanted to take a quart and a half (approx 1.5 litres), you will likely need about 9 insertions and refills, and unless you have longer arms than I do, it can be a bit awkward.
That's why it's so much easier to just fill an enema bag, and control the inflow with one hand to allow the water to come in at the rate and pressure you choose. You can stop and resume the flow as you progress without the refilling and reinsertion after each squeeze.
A bulb syringe is the way I remember the first enemas I received as a child, and I have used a bulb syringe on my own a few times since then when I was staying somewhere where using an enema bag would have been embarrassing or impossible. But once you have an enema bag, you won't want to go back to the bulb.
Best wishes for success for the remainder of your fast,
