Having a baby

Out of nowhere, while doing my microscopy yesterday, I was thinking of trying to conceive before I finish my studies. Yes, I want to have a child. I've been married for 3 years ++ already. Due to the distance, mentality unstable, financial problem etc we have decided to have baby when I finish my studies (my husband is also a student when we get married). But since there are so many things happened that obscured my PhD journey, I can wait no longer. I will be too old then to have the first child (Maybe I am self-concious about the age). I must have child before I turn 30. SO next year is the year to do it. Hopefully next year, I can finish my studies on time. I hope that I can finish all the lab works by end of this year so that I only do write up in the last semester. I am a bit worried about the radiation from the microscope (which is I am not sure how it will affect my baby- must go check this out) as I've been working a lot with it.
It is good that my husband is already back in Malaysia. He will start his career soon and that will help in our financial situation.
The thing that worried me the most is my emotion. Can I take all the pressure by myself? Can I go through all the mom-to-be journey alone without husband by my side? I've been through it before. I don't like it. I had misscarriaged once. I was 3 months pregnant at that time. But back then I was too young and too dependant. I think I have evolved to a different person now. I can be independent, I am more stronger and more rational when dealing with my emotions, I am more active, more matured, and dare to try new things by myself now. Two years living abroad makes me a different person. A lot of things have changed. I am more confident with myself now.
It won't be so bad as I am planning to go back and forth while writing my thesis. But then, I am afraid it will affect the baby if I am travelling too much. It will be 8 hours flight and not only that. I have to take domestic flight too before going back to Malaysia. I have to take into accounts all of these matters.
Whatever it is, to start with, I have to make sure that my husband quit smoking. I want to have a healthy baby, a healthy husband and a healthy life. Next, I have to make sure I do all my work and finish it on time. It is time to get serious again. I want to be home as soon as possible and settling down with my husband. Have our own home, raising kids together, live normally like others. I think I had enough of long distance relationship. 8 years is a long journey. I just have to be strong for one more year. Ya Allah, Please help me. Give me the strength that I need. Amin.
