Well statisticly-from what I have read, an average fertile couple only hasz about a 25% chance of conceiving in any given month- even if you have sex every day.
I almost always remember my dreams and while I do believe that dreams can have meaning and give us a message- they arent always meaning exactly what you would think.
For example, I once had a dream I fell into a swimming pool and I couldnt swim to the surface in time to take a breath. When I tried to gasp for air (still underwater) I realized I could breath under water. It was so cool to just swim all around and be able to breath. I have no idea what this means but someone told me it meant that I am capable of doing things that I thought I couldnt do and it was saying to have confidence in myself- or something like that.
I have strange dreams alot. When I was pregnant I had many dreams that I was breast feeding and in one dream I was breast feeding my pet ferret. I know its funny! I guess since I dont have any kids ( had misscariage) I my pets are like my children.
Dreams are a funny thing.
Maybe you could try a dream journal.
