So confused if I should have more kids next year

Y

I am so confused if we want to have the second child next year. My daughter just started sleeping through the last night last month. We started getting a little more active but I have developed varicose veins which is quite painful. I do have a fibroid too so thinking about health conditions I wanted to be done with having kids by next year since I am already 34! I just don't know if I should wait until the following year. Me and my husband were sleep deprived for past 18 months and are going for yearly physical to get checked on our health. We both have put on a about 10 pounds in weight, trying to shed it off. Not sure what to do!!
