Prometrium side effects

Abbey
For those of you who have had prometrium suppositories prior to getting the bfp, did any of you have extreme fatigue?  I should be 9 dpo and am just miserable like I haven't slept in days.  This is normally my tale tell sign and usually occurs about this early, but wasn't sure if it's just the supplements possibly causing it since it's too early to test.  I know the supplements can make you tired, but this is rediculous. 😳
