I have tracked my cycle for years using the <a href="https://play.google.com/store/apps/details?id=com.glow.android">GLOW app</a> and it’s sometimes within one day of when I start, but usually spot on with its prediction. I’m a week late now and I am experiencing some mild cramping in my pelvic area, but it feels different than PMS. I’m bloated and have the occasional rage swings then I’m good. I took a home pregnancy test on missed day 5 and it was negative. I’m just not sure what to do or how long I should wait to take another one. My mind is also racing to the maybe something is wrong with me...thank you WebMD.
