hi boots... i sort of know how you are feeling.
i have 2 children, i have had a coil since DD was 2 months old. I had a scare when she was 9 months old and was sure i was pregnant. I wasn't. the relief i felt was enormous. which makes me sad and angry with myself as i love the children i have sooo much, but i know in my logical mind , having another is not a good idea.
i had severe PND after DS. fine after DD. i have two lovely perfect healthy children , a boy & a girl..i couldn't ask for more..
my DH has a demanding job and is rarely at home....i am a SAHM , hoping to start back to work in the new year as a doula. I plan to do midwifery at some point. I am getting to the stage i can see getting my life back..and having a fulfilling job and not simply being someone's mum. although that has its rewards, i am only 31 and need to look at where my life will be going . my DD will be at preschool in 18 months then at school, i will have empty days to fill...
but at the same time, the thought of never carrying another baby, or giving birth or holding a tiny newborn in my arms makes me so so so sad.
i think there comes a point where you have to say ,enough is enough in terms of having babies..as babies become children and become teens and need you for a loooooooong time...it is not just about being pregnant , it is another lifetime commitment to someone.
what i find unusual about your situation is that rather than taking a stand either way and either trying for a baby or using effective contraception, you are letting nature decide for you.
IMO you want a baby more than you don't, iFYSWIM
i know there is no way DH would even be in the same house as me if i didn;t have contraception in place ! LOL
i'm sure though that for as long as women are fertile, there will always be a part of you that is saying, go on , have another!
