Is everyone at it like rabbits ? Feeling isolated

I am 34 and been with my partner nearly 5 years , We have a loving relationship we get on great , but we don’t have the hottest sex life at the moment and when u want a baby it can just magnify everything , I am a realist ; I have a teenage daughter who lives at home ,My partner has back issues which he is referred to the hospital for , we r both a bit over weight , I suffer with anxiety and don’t have the best body confidence , we both work . We have sex only a couple of times a month due to everything going on and to be honest I think that suits both of us , this is the reason I downloaded this app to see when I am most fertile so we can plan a bit better , we both want a baby but we both r feeling a bit pressured , everywhere I read people r saying try every couple days , WTF lol should we be at it like rabbits ? It’s just not realistic , I wish we did have it a bit more but he is in pain a lot of the time , and I feel exhausted a lot , I just worry with just once a month if it is ever gonna happen or do I not bother , I only came off contraception a few months ago , I just feel less of a woman that I am not skipping around in my undies ready to hop on at any given moment , I guess in short I am trying for a baby but with a low sex drive , I am reaching out to other woman who don’t feel that sexy when ur cleaning in ur pjs most days , I gave up smoking two weeks ago and am looking at eating healthier to feel better about myself , sorry if this is a ramble , any advice or shared experiences would really be appreciated I feel really alone in this right now , if I talk to anyone I know about it they seem to just tell me how much they r getting and it really don’t help !
