You could try taking it vaginally, there are usually fewer side effects that way. If that doesn't work there are two options. You could try it cyclically so take 200mg for 12 days a month - you'll have a bleed but you can tell if it's caused by the utrogeston if you only feel bad when you're on it. Or you could carry on with 100mg continuously but take it every other day. This works best if you're on a low dose of oestrogen and should be done with medical supervision in case your lining builds up. How much oestrogen are you on?
