long post.. opinions?

Hey ladies! I need some opinions.. I had my mirena IUD removed on Friday to TTC baby no. 2, I had 0 bleeding or spotting after removal, I actually didnt even feel it! My son is 19 months and I had it placed at my 6 week visit, so I had it for about a year and a half. I did not have a cycle on it up until about September.. I was breastfeeding until last month so that may be why also. But starting in September I started getting a SUPER light period every month I mean lasting only a day if that.. If was more like spotting but it was something and it was the same time each month. So, I would be due for my cycle this week and the doctor said it may be a little heavier but not too much since I JUST had my IUD removed but he did say the one after this should be a normal heavy cycle. So since yesterday I've had really light spotting, I think it's almost done now because it's brown tinted. But no actual heavy flow. This is how it was on the IUD. Since my time frame is lining up should I go ahead and assume this is indeed my cycle? I am actually hoping that it is so that HOPEFULLY two weeks from now I would ovulate and we can get to baby dancing. I also should add that I have had a couple very tiny clots but nothing major  in with my spotting. Thanks in advance!
