Hello, and I hope I can help you today.
Many of the new, over-the-counter
pregnancy tests are so sensitive that they can detect pregnancy hormone even before a missed menstrual cycle.
So if you perform the test correctly, and interpret the results correctly, it is unlikely to be a false positive. However, the reason OB/GYN's do not usually recommend testing before you have actually missed a menstrual cycle is that sometimes a fertilized egg can temporarily make pregnancy hormone and then not implant which can result in a positive pregnancy test and a and then a normal or slightly late period This is called a chemical pregnancy and can get you excited about being pregnant and then disappointed.
So, I would just stop drinking alcohol, take
prenatal vitamins, and possibly repeat the test after you miss your menstrual cycle.
I hope that I was able to adequately answer your question today, and that this advice was helpful.
Best wishes, and good luck with the pregnancy,
Dr. Brown
