Its been 20 days since I missed my period, tried 3 tests on 1st 10th and 19th days of missing the period.. all came negative although now I feel there might have been an almost faint line yesterday. I feel nauseous , my breasts hurt like they're sore and I get cramps on and off.. I could be pregnant right ? Is it possible ?

1st day you missed was a waste of the test,way too early.

The 10th may be OK, but some women need to wait longer,

There is either a line or not a line, try another test, make sure it is first thing in the morning when you first get up, for best results.
