I don't use the Ovia app, is it any good? I'm not sure which one it is that I use, fertility friend maybe? I don't log much in it though to be honest, just period days to keep track of things. I don;t bother with temperature, and mucus and all that stuff as I figure recording it isn't going to make any difference as to whether or not I actually get pregnant. I do log positive ovulation tests though actually, and sex if I remember.
I got a positive ovulation test today, but trying to convince DH into dtd last night was hard enough, so I'm not sure what we'll do today. I'll have to up my game! I get that he's tired etc but I do get a little frustrated that if he's not in the mood I have to put in all the effort, it would appear that my mood is not really relevant. He doesn't mean anything by it, it's just hard being forced into it on certain days I guess.
I was never totally convinced by the 'relax and it'll happen' line, but so many people seem to say it that I suppose it got stuck in my head. It will happen when it happens though, regardless of what else is going on.
We went through the process of buying our house when I was pregnant, the sale went through when DS was 6mo. It wasn't great timing but our landlady wanted to sell and we didn't want to move. It can be done, and sitting in the bank talking to the mortgage adviser and saying 'sorry what childcare costs?' with a massive baby bump under my dress was rather amusing 
I can understand you feeling rather conflicted about it all, there is no right or wrong choice and I can imagine you are still rather emotional about it all? What does your DH/DP think?
