Just started cyclogest pessaries as I can't seem to tolerate utrogestan. I've found that almost instantly, I've got heartburn, am bloated and am not going to the bathroom. Tried various means to alleviate the constipation but to no avail. Just wondering if anyone else has suffered similar. I feel nauseous and look like I'm about 6 months pregnant. Only been about 2 weeks really so I'm hoping things will settle.
