Have to decide this week if I'm having number 4 arghhhhhhh

[KatieDD]

Help please !
For:
3 is a funny number
Would quite like a boy, have 3 DD's so maybe one more shot at that lol
We have 3 so one's not going to make a massive difference.
I just want one.

Against:
Would need bigger car
Hubby is far from keen
MIL will have a fit, actually that's a plus
Am really rather tired most days even with 3
I am very hormonal whilst pregnant, fine afterwards but a miserable bitch during.
Would need IVF costing £6,000 and in all honesty my kitchen and bathroom are falling apart.

One of my husbands colleagues went to a clinic in Spain to get his sperm washed, to ensure the gender of their last child. Extreme.
My dh would have gone for no 4 if ds had been dd3, but now he has his boy he is adamant that 3 is enough.

We'll see.

I can see advntages to both sexes so am leaving that to chance.
Next question on my mind is I can only afford one go at IVF really so do I have two embryo's put in knowing DH will make me leave one at the hospital if it's twins
