Positive Pregnancy Test and then a Negative Pregnancy test four days later?

Tuesday morning the day my period was supposed to start I took a Clear Blue Easy digital test and got a Positive result. On Friday morning I took the same test again out of the same box and this one showed up Negative and I am starting to spot but it doesn't seem like a normal period. Maybe I am just wanting to be pregnant so the spoting doesn't seem normal. I have an appointment on Monday with the OB-GYN. Any ideas? Can I be pregnant?

alright, so I have been "feeling pregnant" you know the usual symptoms: enlarged breasts, cramping once in a while, headaches, dizziness (now that seemed to kind of passed) nauseous, tired all the time...and I have a very very light time of the month, it has been about a week and half since then, I went to the doctor the day after it stopped and he said it was still too early to tell, its been about a week since the doctor visit, and I took a home pregnancy test this morning around 7:30 am, and when the result started showing up it said positive for a few seconds to a minute ( I was so excited I didn't keep track of the time), then it vanished, im not sure whether I am pregnant or a should wait a bit long to see if I am or not?

if you take a test and its positive, then you are pregnant, its detects it in your urine, sadly though you had a chemical pregnancy which happens before your period, and you miscarried...which is why there was more blood then normal

Ok Ladies, here's what I know so far from my own experiences:

Home Pregnancy Tests read a hormone that your body secretes AFTER implantation (this will be important later) called HGC. When sperm meets egg way up in your fallopian tube, you are technically pregnant but your body will not show any symptoms-- at that point, the tiny blob of cells is travelling down your tube and to your uterus. We'll call this day 1, and it usually around day 15 in your cycle. It can take anywhere from 6-12 days for the cells to make the trip to your uterus (Day 21-28). At that point, if all is still going well, it'll implant into the lining of your Uterus-- at which point you MAY experience some light bleeding called Implantation Bleeding. Not everyone has it, but it is why sometimes you think you just had a light period but you are actually pregnant. After about 3 days of Implantation (Call this day 17-28 of your cycle), your body starts producing the hormone HCG to trigger the changes that signal your body to prepare for pregnancy-- swelling breasts, thickening of the uterine lining to support the pregnancy, morning sickness, etc. Once the HCG is at a level where it can be read with a blood test (3-6 days after THAT) but only at a clinic that does a blood test. 3-6 days after THAT there is enough HGC in your system that passes through your urine that you will be able to see it in a Home Pregnancy Test. So it could be DAYS after you are "officially" pregnant to show up positive on a home pregnancy test.

So the short version: you can pee on a stick at home and show a negative and still be pregnant.
You can pee on a stick at home in the morning and it will be different than in the evening.
You can pee on a stick after drinking a lot of water and it be negative since HGC is water-soluble even if you are pregnant.
You can pee on a stick at home and show a positive (urine is concentrated), but then later on a negative (urine is dilluted), and you might still be pregnant.
You can be pregnant, but then not carry to term (a lot of the time the cells won't divide right or there'll be a problem so the body will naturally miscarry) in which case... you showed positive, then negative, then had a period.

For those trying to be pregnant: Good luck to you!
For those who hope they're not: get to a clinic or a doc and have them test your blood to make sure.
