Accurate estimates: Ultrasound dating scans in the first trimester, such as at 8-11 weeks of pregnancy, are very accurate... meaning plus or minus one week. Especially if the doctor feels the fetus is growing appropriately for gestational age through the course of the pregnancy, the original dating estimates were likely very accurate.

A 39-year-old female asked:

My boyfriend & I are trying to get pregnant. I'm on Zoloft (sertraline) & my doc is having me get off it slowly; 1 pill every other day for a month & then 1 pill every 3rd day until gone. Does this sound reasonable?

Yes, it's great.: It's best to taper off the zoloft (sertraline) and your doctor has an excellent plan.

Check a preg test : Over the counter pregnancy tests are cheap and reliable. Go do one and then you will know and you won't have to worry about it any more. If you don't want to be pregnant see your doctor for effective birth control.

A 23-year-old female asked:

Is it ok to make a 2 month old baby sit upright. Won't it hurt her back bone?

Not natural: Sitting is not natural for a 2 mo old. Laying on a surface semi-upright is. If you sit him supporting him (like on your lap while holding him), then it is ok. I would not advise sitting him by himself on a high chair for example.
