Hi laila, i remember you from ttc threads!hope things are going well? I got a bfp a wk ago but have been on cyclogest progesterone since 3dpo. Its taken vaginally and i think its more or less the same as prometrium- have to admit it makes me so drowsy, i cannot stay awake in the evenings-about two hrs after i take it im just exhausted. Also i find it quite messy and inconvenient-i try lie down(not easy with other smallies) for 30 mins when i take it as it just seems to leak out otherwise. Quite headachey and achey joints too but these seem to have settled down now. X
