When and Why do Pregnancy Tests show Positive Results?
Posted: 08-21-06 16:59pm

I have been trying to get pregnant for about a year now. It is difficult because my periods are irregular. I have been anywhere from 30-42 days. I used to experience bad cramps and also had pain on one side when I was ovulation. I no longer have cramps nor the pain in my side. It's been this way for about 2 years.

I usually get a day or two of spotting before my cycle starts which is the only way I know it is coming. This month, I started spotting on day 38 of my cycle and it lasted about 6 days. It was nothing like my period, very light and brownish in color. I've been very tired lately and get hot flashes at night.

From what I understand, if I was pregnant the test would be positive by now. I took one this morning and it was negative. Is it possible to be pregnant and not test positive until days after missed period? Could implantation bleeding last for 6 days? I am nervous that I am going through early menopause. Your advise would be greatly appreciated.

It seems that you are suffering from sterility because you have been trying to conceive without success for more than a year. It is not clear whether or not you are ovulating, so you can visit a gynecologist to confirm this. A vaginal examination, hormonal analyses, a vaginal ultrasound, and a Pap-test are the necessary diagnostic tools for evaluating the condition.
Regarding pregnancy tests: a pregnancy test detects the hormone "human chorion-gonadotropin" (hCG) that is produced by an embryo’s outer layer, the chorion. Production of hCG begins after the implantation of the embryo on the walls of the uterus. Implantation occurs 8-10 days after conception (around ovulation) or 5 days before the next period is due. Conception can occur 12 hours (at most ) after ovulation. If implantation is successful, the next menstruation is halthed (missed period) and that is the first sign for a woman that she might be pregnant. During those 8-10 days between conception and implantation, a test may be negative although conception has occured. Likewise, a test can be positive during the 5 days before the next period is due without symptoms or signs of pregnancy (no missed period).
Such thing like “implantation bleeding” doesn’t exist!!!
You are not in a menopause. Menopause is defined as lack of menstruation for more than a year.
