hi i am about 24 weeks pregnant with number 2. i feel like the worst mother as i havent gone for a check up with an obgyn, i went to our local doctor and the babies heartbat was fine, i am having a scan done next week. i am scared that not everything is fine as i have been sick and constantly tired through my pregnancy, my first pregnancy was a breeze. everyone says that i am fine and so is my baby as all pregnancies are different. is it normal that not every mother to be sees a doctor for every pregnancy? is there anything i should know or be doing for the rest of my pregnancy. thank you.
