Make an appointment with a fertility doctor (RE) and request a fertility workup. These are a battery of tests that will determine if you have reproductive issues. The doctor will then work with you and your spouse/significant other to achieve a pregnancy. Good luck!
No, they can only get pregnant with "try for baby".
Make them relax on a bed with the Sim who you want them to get pregnant with, then have them "try for baby" - if they are pregnant there will be a lullaby. Although having a pregnant vampire might make them die, as vampire Sims cannot go out in sunlight or they burn and die - and baby Sims are annoying as they can cry at any time.
Try for baby is woohoo but the female sim usually gets pregnant afterwards.
You have them try for baby on a double bed
No, that is a ridiculous question. You would have to be physically in love and you cannot be related. That is just wrong. Do not even TRY to attempt to do this, this is physically impossible.
No, trying to have a baby can't change your menstrual cycle - think about it, your body is designed to try for a baby every cycle, it cannot tell when you have actually decided to try to get pregnant, not to mention it would make little sense for trying to have a baby to change your cycle. If you want to try for a baby then it may help for you to learn the basics about how babies are made first.
You need to WooHoo or Try For Baby to make your sim pregnant in Sims 3. If you don't won't to try them out then adopt a child.
Yes. Just Try For Baby.
no but if you do your baby can die
No
When they "try for baby" at the end sometimes you can hear a little lullaby noise and that will say if it was successful or not. Also in exactly one day after they woohoo they will get nauseous of unknown causes.
What are you talking about? Try having baby and put it up for adoption
