Starting chemo

Hi! I am new to this site and this is my first post. A little back story on me......I found out i had colorectal cancer after an exploratory surgery was performed on me the day after i delivered my son. This was in September of this year. I had issues during my pregnancy and they were all blamed on my pregnancy and never looked into. During this surgery they found that my appendix had burst (where my cancer was found) and my right ovary had burst also (cancer was found attached to my ovary as well). They decided to wait a month and go back in again to take parts of my intestines and lymph nodes to see if the cancer had spread. Luckily that came back negative. I am cancer free as of right now. However, the oncologist i went to wants me to still do chemotherapy “just in case” for 6 months. I am a stay at home mom of 4 young kids that i am very active with. I am terrified of doing chemotherapy for many reasons. I am struggling with the decision of whether or not i should do chemotherapy if i am cancer free. I am going to meet with a second oncologist this week for his opinion but for now if anyone has any tips or suggestions for me i would greatly appreciate it. Any words of encouragement will gladly be accepted and appreciated too. Thank you for taking the time to read a short glimpse of my story.
