Is this weird or normal?

I was on birth control for about 1 year and 1/2 to almost 2 years.. A few months ago, my SO and I decided that we would like to start trying soon.. So I talked to my doctor about it and I stopped taking my birth control after thanksgiving.. I waited until the pack was done to stop.. My periods I have had these past few months were okay until last week.. It was very short.. I usually have it for five days (first 2 days are heavy and last 3 are average).. I only had it for 3-4 days So my question is, Is that Normal when you get off of birth control?
