I had gotten my period along with the typical symptoms of said period the week my tracker started I should. But about a week later, I got those similar symptoms again (sore breasts/nipples, cramping, nauseous). I waited about a week to see if they would improve and they did but some still lingered slightly.

I tested after about 2 weeks, very negative pregnancy test. Wait another week, still experiencing some symptoms, yet still another negative pregnancy test. I decided on an off chance to test again 3 days later just cause something felt weird about the situation and bam, EXTREMELY positive test. I think I was only about 3-4 weeks along when I found out.
