How do I predict start of cycle when not having a period?

So, I found out that I am not ovulating and been having constant bleeding - so I have no clue when the start and end of my cycles are anymore.
I am being put on Clomid to start ovulation in hopes of conceiving.
How can I predict the 1st day of my cycle?? (Aka the 1st day of a period.)

MichiganGirl - in respone, the directions for clomid say to start it on Day 5 to 9.
But I have no idea when days 5 to 9 are :(

Must not be clear enough.
Ive been bleeding for 4 months - constantly.
So I have no idea when my cycles start and end!
Hence, I cant just use the old "first day of bleeding" thing

With clomid, you'll likely ovulate 5-12 days after taking the last pill. So, if you haven't conceived, your period should start around 12-14 days after ovulation.

very first day you bleed is first day of your cycle, until the day before your next period. just keep track if they are irregular and you will see some pattern
