I am a month late I took 7 pregnancy test all positive but now the day I should be on my period is on Tuesday and I'm cramping a little more frequently then before. Could I just have skipped a month?

If you got 7 positives.. I have to tell you you are pregnant... if you still aren't sure... get your Doctor to give you a test.

False negatives are common if you don't to it right or do it early... false positives very rare... for one... for 7 in a row... astronomical.

Pregnancy tests only turn out positive in the presence of HcG, the pregnancy hormone. Your body only produces this hormone when you are pregnant, so false positives are impossible.
Sometimes people get negatives when they actually are pregnant, if their urine is too diluted (they drank a lot of water for example) but a false positive, particularly 7 of them, just doesn't happen.

It is not uncommon to have some spotting in pregnancy, particularly early on. Also, your body goes through a lot of changes in pregnancy, so you can feel some discomfort. The rush of hormones has a lot of impacts even early on, and that might be what you are experiencing.

Cramping and spotting can also indicate that you are miscarrying, but I doubt that's what's happening from your description.

You need to go to a doctor. Early in a pregnancy, there's a lot of advice you need and also you need a prescription for prenatal vitamins, which are important for preventing some very serious complications like spina bifida, which can be very disabling to the baby. If you are not planning to parent the child, you can get some advise on where to turn.

Stop running to the store for more pregnancy tests - you've got your answer. Next stop, the obstetrician's office.
