i am a week late and took a test last night..

i have read a question about what time to take a test and why does it matter.. well i took one at night and i am a week late, it came out negative. does testing late at night after being a week late still have an effect on your hcg levels?

  • yes it does. you should do it first thing in the morning once the urine has "sat" all night.

  • In some cases, a woman may drink a great deal of fluids before collecting a urine sample, thereby diluting the amount of hCG present in the urine. If your schedule prevents you from using a first morning urine, avoid drinking a lot of fluids before testing - and try to hold your urine for several hours before collecting.
    hCG develops at diff. rates among women. Some women can easily discover if they are pregnant well before their missed period. Other women may need to wait a bit longer. The amount of hCG in your urine doubles each day following the implantation of the fertilized egg in the womb. An "average" hCG development rate, the crest of the bell curve suggests that hCG levels will reach 20mIU/ml/hCG at seven to ten days following ovulation. Again, this is an "average", so many women will fall on either side of the bell curve peak.

  • there may be reasons for having a missed or very late period that have nothing to do with being pregnant! For women with irregular cycles, being late now and then is part of the "normal" pattern. Predictability is less of science and variation in cycle length is the rule, not the exception. Other factors that can influence a missed period are, of course, things like increased stress, anxiety, or sleeplessness. Stress and anxiety produce specific hormones in your body - stuff like cortisol (the hormone behind your "fight or flight" response) or adrenaline. Long periods of stress or anxiety can affect the balance of reproductive hormones and delay ovulation or the onset of menstruation. This is pretty normal stuff today, in our stressed out world. So if you are stressed, don't let worrying about cycle regularity add fuel to the fire. Also note that travel and jet-lag can cause period-lag as well.
