Weight loss during pregnancy?

Hi ladies. Not long found out I am pregnant with baby number 2. My son is 19 months old and since having him I have lost around 60 pound. I did this within the 1st year of having him and have basically remained the same weight since then. I am so worried about piling on the pounds and think I’ve probably already put on atleast 8 pound from over eating. Going to start monitoring my calorie intake today. Would like to steadily lose a few more pounds until my second trimester and then try and maintain (obviously not including the weight of the baby) am I being ridiculous?
