So, according to my period tracker on my phone, I ovulated 17 days ago, I have a generally short cycle (24-25 days). I am now 3 days late for my period and don't know what to think-- my fiance and I dont use protection and haven't had any pregnancies before so its hard to believe I am pregnant. We are very active though so it is possible. I've been having cramping sensations not like a period but more like a sharp faint pain, havent been very hungry and tired. I took one test but the line in the second box didnt even show until the next day so I dont feel like it was valid not to mention it was probably too early. What do you all think?
