Most likely you are not, pregnancy tests are very accurate. But if you have irregular periods often, you should visit your doctor.
You guys may have become irregular or u maybe be pregnant. Lots of women get blood test to see if they are prego.in lots of cases blood test pick up the hormones better than the sticks sometimes the hormone isn't concentrated enough n your pee for the sticker to ready it. You guys should most definitely go to the doctor tho.
