Werid Period?

I've been doing the 6 week body makeover program for 2 weeks now and doing well. It's a great program and is healthy & safe. However, it is making my period weird.

I was originally supposed to have my period at the beginning of June, but did not have it. Late in the month I did have it for approximately 2 days... and then it stopped. Now for the past two weeks I have been bleeding, but very inconsistently. For example: one day I won't bleed at all, the next I won't bleed in the morning, but will in the afternoon for a couple hours then stop again, or I'll just have real light spotting throughout the day with a quick heavy burst sometime during the day. This is getting on my nerves, and I'm afraid something may be wrong. I know that this program [[cutting out soda, salt & sugar along with other things]] has thrown my body off. But how long will it take before it is back to normal?

I hope it's corrected before 2 weeks... I'm going on a week vacation at the beach and would not like to have to keep a pad on the whole time since I can't wear tampons.
