I usually have a regular period, 28-34 days cycle. But this month i have it late. I didn't have any change in may daily routine. The only change i made was the combination of acai berry and colon cleanse pills i been taking in my diet. But other than that i really didn't change anything. I have always been safe with my boyfriend when it comes to sex. In fact the last time i had sex was the last day of my last period (which im supposed to be not ovulating yet) and it was a safe one, and i didn;t have any after that. I usually take parsley tea if i'm late and i usually had my period within 24 hours i took the tea. I took parsley tea two days ago but no result, i changed it with dong quai since yesterday and no result yet. I also usually have all the PMS syndrome during ovulation and until i have my period such as sore breast cramp etc. But i didn't have any of those symptoms this month. i wonder why is that. Can acai berry combined with colon cleanse have this kind of effect on your cycle? i haven't had my period until today and i'm two days late already, i'm so worried....
