Please excuse the awful name change but I have been driving myself insane all day.
You see I am on day 33 and normally about 28 days.
I've got three children the youngest is 17mth and does not sleep. Dh and I hardly have sex due to being so wrecked most of the time.
I always mark a week out on the calendar which is roughly my ovulation date and we avoid it. It's always worked for us, he does not ejaculate in me 
we planned out three children so it's not been a bad method... up to now?
All today i've had yucky taste in mouth, I do not have my usual pmt or spots, and my temp is 37 normally I am 36.5. I am probably reading too much into this.
I mentioned my period had not come yesterday to my dh and he looked really worried and said that he would have a nervous break down and could not cope with another baby. he wanted to have the snip recently and i talked him out of it because it felt wrong. But I am happy with my three.
I know people will say if you did not want anymore then we should be more carefu and if my period comes I think I will encourage him to get the snip.
But if i am pregnant then it's going to really bring a lot of problems, my partner will not want the baby but knows that I could never abort a baby and if i did I would never get over it. So we would have the baby and be even more wrecked. We live in a two bed for a start, our car could not fit another baby, i am just starting work again.
But I do have all my baby things still so we would not have to buy anything, i breastfeed for the first year. But thats only the first year clear.
Could I cope, would I be a bad mum trying to manage four children. My oldest already feels a bit pushed out with the youngest always getting the attention.
I can not imagine telling dh, I reckon he would be so upset. It's our own fault, all my children were conceived with joy, I would want any baby i have to be wanted just as much as the others.
