Help me please

Ok y’all help because i am surely confused. Last cycle we tried and i got a positive and started spotting that same day. That turned into brown blood for days and got a little heavier but not like my actual period it was very light but enough that it would fill a liner. My tests went back negative so i thought it was a chemical. Now my app says i ovulated and i felt bad cramps about 2 days ago. But this is my test today when my app says i ovulated on the 28-29
