I need energy!!

Hello ladies! I am 6 weeks today and I wanted to know what prenatal vitamins do y’all recommend? I have no energy to get up, I feel very weak and I just want to be laying down in bed all day. I have a 3 year old so in reality none none of that can happen. Last time I had some blood work done my iron levels were somewhat low. If any of y’all know a good product that would both help me with my iron levels and my baby. Please let me know. Many thanks 💖
