I dont track when i ovulate with opks or anything like that but today i bought one of those dollar store cheapies and to my surprise there was two lines one being darker then the other. but the app that i have that tells me when i ovulate said i did on the 9th so im confused maybe the app is wrong and i actually ovulate in the next coming days any feedback would be great

side note: i do have af type cramps and im nauseous boobs hurt a little and upset stomach i dont know why tho.
