IUD removed and trying after 40

So, I turned 40 two weeks ago and had my IUD removed. My new hubby is 28 and we would like to try for a baby. I have PCOS so my first baby took 3 1/2 years. Two years later, second baby took 3 1/2 min. I’m about 80 lbs lighter than I was then so I know that should help. I spotted lightly after it was removed, then started what I thought was my period about 2-3 days later. Now, 2 weeks later I’m bleeding again. Is this normal? Any suggestions on what to expect? I had the IUD for 5 years and no periods. Thanks in advance!
