First planned pregnancy and confused since I've had iud in for 7 years!

I've been using the iud method for past 7 years. My husband and I decided we wanted to have a child together so on March 3 I had it taken out. I started bleeding and it was heavy then it would go to more of a spotting back to heavy back to spotting up until March 8 do I classify that as a period? Have any of you conceived right after iud was taken out? This is our first planned pregnancy (we both have children from pervious relationships) so it's all confusing to me and I wanna make sure I'm doing everything right.
