I'm 7 days late for my period took 4 home test 1 positive after the limit 3 not, with some spotting, could i be pregnant? when to test again?

Maybe in 3-5 days: Home pregnancy tests are easy to do, fast, and highly accurate, but not 100%. Maybe it is a tad bit early at this time. I would suggest repeating in 3-5 days to make sure. If you are pregnant, there is a very good chance that the hpt will show postive after 5-7 days of missing your regular period. You are 7 days late, but this may just be a later than usual--it happens. Consult doc. Good luck.
