Well for a few weeks I have been having pregnancy symptoms.
I took 2 tests on the 19th and one on the 20th.
I started my period the 19th at evening and ended 3 days later.
But those 3 tests were negative.
Also I chugged a lot of liquids before taking those tests.
I took 2 tests on the 26th
and one this morning.
all three negative.
Also conception would of happened on either the 1st or 7th or 14th somewhere in there.
The symptoms I'm getting are
+nausea
+back aches
+tender breasts
+i have pudge, and it's not soft feeling
+certain smells make me feel ill
+i get dizzy
+i'm really moody
I'm certainly no professional, but I think it's pretty uncommon to get that many false negatives. If you really feel as though you are getting false negatives though you might want to see the doctor so you can get a blood test.
