I took hCG drops about a month ago, stopped about 15 days later. Yesterday I took a home pregnancy test and it came back positive. Could it be false?

It's likely real: Urine pregnancy tests are very accurate, so the next step is to contact an ob-gyn doctor (or primary care doctor, if one does not have an ob-gyn doctor).

What are the chances of home pregnancy test giving an accurate positive result 5 days before missed period?

What are the chances of home pregnancy test giving an accurate positive result 5 days before missed period?

Unlikely: Most home pregnancy tests (hpts) claim to be 99% accurate on the first day of the missed period. However, research suggests that most hpts do not always detect the very low levels of pregnancy hormones this early. Most hpts can accurately detect pregnancy 1 week after a missed period. Read more

What are the chances I got a false positive home pregnancy test? I am now spotting and cramping but I've lways been irregular w period. Hope I'm preg!

You probably are!: A home pregnancy test has a very low chance of being false positive. With spotting and cramping it would be wise to get a blood level of HCG - measure the quantity of pregnancy hormone in your blood. That can tell you a lot more. Read more

At 12 days post ovulation will a home pregnancy test give an accurate reading?

Take test: Home pregnancy tests are very accurate and this medication will not affect the test. They are the same tests used in a doctors office. They can detect a pregnancy 7-10 days after conception. The best time to take one is when you miss your period. If you doubt the result you can repeat it in 1-2 days. If you were pregnant the hormone level would rise enough for detection. Read more
