I usually have a period every other month, but last month surprisingly I had a period that came right on time (April 25-28) according to my <a href="https://play.google.com/store/apps/details?id=com.glow.android">Glow app</a>. Also had a period March 26-31. And my periods are never consecutive anymore since I had a miscarriage last March. I'm now on CD 36 and AF is nowhere to be found. I'm having slight abdominal cramps, and cramps similar to period cramps but no bleeding and they aren't constant. I can usually tell when my period is about to start. Has anyone experienced this and been pregnant? Don't really wanna get my hopes up.
