So I have 2 different <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">period apps</a> and one says I'm 4 days late and the other says I'm 2 days later. Yesterday I had a small amount of blood after I peed so I thought I was getting my period but today I haven't had any blood. My period is always on time and I'm not sure what's going on. I took a pregnancy test 3 days ago but it came back negative. Has this happened to anyone? Could I still end up being pregnant? The hubby and I have been trying to have another kid but no luck yet. Please help.
