Need some advise/thoughts!

So i never really lost much weight after my son i am 5’2 and I’m 144 lb! But before i had my son i was 125 so i was able to gain all this weight during pregnancy which was 166 at the end on my pregnancy! Now I’m trying for baby #2 and I’m worried about being over weight since I’m starting at 144 now!!!!! Any advice, comments!!!!!
