I took the pill for three rounds, and then i got it "normall" at the same week last month an dthis month, when i wasnt on the pill. The only thing is they were soooo light, would last from 2-3 days, and i would only use the equivalent to one tampon a day, not even filling the whole thing up. There is NO way i could be pregnant so i am ruling that out. Should i go back on the pill to make my periods regular?

What do you mean by taking the pill for "three rounds" ??? Do you mean three cycles/three packets of pills?

I'm not sure if this is what's happening to you, but going on and off the pill will cause irregular periods.

You can try going back on to make things regular, or just wait it out. If you stopped taking the pill, it may take awhile for things to get back to normal. Talk to your doctor if you continue to worry about it.

i meant three packets of pills
