Pregnancy Spread

I found this spread here. I wish there was more interpretation done on it. It seem like the blogger has abandoned her blog however.  I am also confused about the months in this spread and how they correlate? I am also not getting a very clear depiction or interpretation.
Here it is:

1

2 _ 3 _ 4

5 _ 6 _ 7

8 _  9 _ 10

11 _ 12

1. Conception

2. Month 1 - January

3. Month 2 - February

4. Month 3 - March

5. Month 4 - April

6. Month 5 - May

7. Month 6 - June

8. Month 7 - July

9. Month 8 - August

10. Month 9 - September

11. Labor/Birth

12. Sex of child

I am really thinking that the deck I am using is crap. I think I need a more traditional deck instead of the goofy one that I bought (it is a housewife tarot deck).It doesn't make much sense on some issues and seems to be downright wrong when trying to use another system to interpret a spread. Then again, I may just be really tired and not focusing on what my goal is. I am going to try and interpret this again over the next week. Any suggestions or ways of interpreting are welcome!
