TTC for 4 months

Well technically 4 months, that having sex in the approx fertile window but seems longer. Too much planning that's the biggest culprit of our sorrows and worries. Started my AF today and just felt like howling away. But now I realize that just putting to much pressure on one's self. So how total change of plan. Try and have fun with DH whenever we can during all the business trips and no planning. Or atleast try not to. Anyone sailing in the same boat of self pity and then realization mode ?
