Need yalls opinion

So had a period march 19th like normal. Didnt have another period until may 28th. Went 71 days without which normally i range 25 to 52 days but typically the 30s. On the 26th i got two pregnancy test vvvfl and then the next day nothing. So I thought maybe it was a chemical. Since my period ended my boobs have been really sore and they seem to be even more sore at night. My last period was heavy if not a little heavier than normal and cramps were worse than normal. Could I still be pregnant? If I was to begin with. My test says no but idk why my boobs are sore. I am in the middle of my predicted ovulation right now according to this app.
