so last month i had my period on the 15th but my periods are irregular so glow put my expected period as the 19th & i still haven’t started. i took a pregnancy test on the 18th which was negative. I’m not <a href="https://play.google.com/store/apps/details?id=com.glow.android">tracking ovulation</a> but my husband and i had sex all month long. i’m officially 5 days late according to glow though. what should i do? i have slight cramping here and there but no sign of blood. i’ve had headaches and nausea some but that’s about it.
