Trying to BD during the fertile week

Sarina
Im 36 and we just got married last year. Been trying for nearly 6 months now but no luck yet. But I also noticed we only BD maybe 1-2 times during my fertile week so the chances arent that great either.
Are we the only ones who are tired from work? 
Usually he's tired from work or I am so we just can't BD everyday during that fertile week. But this month my fertile week lands on our 4 day holiday weekend and so I am determined to try to BD 4-5 times during my fertile week. So far we BD twice already.
Gosh I hope our chances increase this month. 
I just keep worrying it wont ever happen. But I think this is the first real month we are trying harder so hopefully it helps somehow to increase our chances.
