Ready to ovulate and SO is too tired :(

Lauren
Hi Ladies, just a little rant really. My SO has been doing night shifts this week and doesn't get home until 3am or so..normally he is all over me when he comes home, and it is more than welcome this week as I should be ovulating any day now..but he just gets in bed beside me and says hes too tired, or last night he is too full..I understand he may be tired but he said we could try for baby number 2, I've ordered my tests and so far we've had sex once early hours thursday morning..anyone else having the same problem?
