I will tell you exactly how it is...
She talking about getting tests because her body clock has started ticking and its becoming baby time for her! What you will notice in the forecoming weeks/months:
1) Everything small will becime cute, such as small dogs, clothes, shoes etc however she will start to find small babies cute also. This will become very obvious to you as it will become more frequent.
2) She will start hanging about friends/family who have children more than usual
3) She will start wanting sex all the time..oh and the daily pill she is supposed to take she will "forget" from time to time and if its the injection/impant she will delay going for it if not at all.
4) You being drunk etc will not be a problem as she knows when your drunk you will fuck her brains out, infact expect bottles of wine waiting for you at home.
5) Expect her to be nicer to you than normal until she gets what she wants (sex)
Either way she will get what she wants or she will go mental after a while if you don't get her up the duff and take her frustrations out on you and eventually she will leave you if you fail to give her children and its "your fault" as your sperm are on a perm holiday.
My advice if you are not ready yet, double your gear doseage, take lots of Deca etc and make sure you shut down your spuds, go the doc without her, when you get your results and they won't be good, the doc will give you a load of HCG etc, stick it in the fridge and tell her "it's a little low, but working" and get the get shit loads of sex until she figures out your a lieing girl. Then you have 2
options when your relationship hits the brink:
A) Come off the gear, shoot HCG until you piss it and give her a good stuffing and give in
B) Trade her in for a younger version who don't want kids
On another note, somme of my friends been on gear and had kids no problem, some come off it for a while and then had kids, some had to have allsorts of treatment. Depends friend, all you need to know is she will turn into a bitch when shes up the duff, so enjoy!
