I'm 10 days late on my period im very confused because my period is always on time almost strictly a 28 day cycle. My period was due june 17th im now 11 days late me and my husband are very careful we only use condoms but always check them well. Ive taken 3 tests and all 3 have been negative. Shouldn't I have a positive result by now if I am pregnant? Idk what to think at this point and im very anxious!!
