Mam: Pregnant 21 weeks (Baby 19 weeks)
You are really showing now, your uterus is above your navel, and strangers may ask you, ‘are you expecting?
You are really showing now, your uterus is above your navel, and strangers may ask you, ‘are you expecting?’ You’ve gained up to fourteen pounds. 
You're probably feeling pretty comfortable these days. You're not too big yet, and the usual discomforts associated with early pregnancy are, for the most part, gone. If you're feeling good, relax and enjoy it while you can — the third trimester may bring with it a new crop of complaints.
You may have more oil production in your skin which may contribute to spots. If that's the case, be diligent about washing well with a gentle soap or cleanser twice a day, and make sure that any moisturizer or make-up you use is oil-free. Don't take any oral acne medications — some are very hazardous during pregnancy — or use any topical acne products without first checking with your doctor or midwife.
To help prevent or minimize varicose veins, exercise daily, prop up your feet and legs whenever possible, sleep on your left side, and if possible wear maternity support tights or stockings which will minimise aching legs at the end of day.
