Light period questions

Hello ladies, I’m hoping someone can help. I’m 37 years old. I always had light periods. I had my daughter 13 years ago and started on birth control right after. I had no periods because of that. Then I decided to have the mirena iud. I had it for 7 years. Never had a periods while on it. January I had it removed. Since then I’ve been having very very light periods. Like 2 days and I do t even need pads. A liner will do the job. Anyone having the same thing. I want another baby and I’m afraid that would interfere. My periods are very regular though. I’ve been getting it every 27-28 days. Please let me know what you guys think. Thank you
