Welcome to BB.

I think that what you are thinking is completely normal.
As PPs have said, it takes many couples 6-12 months of TTC before falling pregnant. When I first got anxious about TTC my doctor told me to come back only if we had tried TTC for 6 months with no success, i.e. that it is completely normal for it not to happen straight away.

GL with your TTC journey. Hope it happens for you real soon.
