Helpppp what's going on???

Kaila • Mother of 2 amazing boys!! Sirwayne Jr and Kyler!
So 1 app said I was supposed to have AF yesterday 6/4 and another app says tomorrow! 6/6! I've had 1 negative HCG test which was taken on Wednesday 6/3. I usually have sore breasts prior to AF but I do not!! I have had mild cramping but no spotting!!! I've been on Trinessa birth control for 5-6 years and I stopped those during my AF in April. Any ideas what's going on?? Is my period irregular now or could I be pregnant and its just not showing up on tests yet? Need some opinions from you ladies please!!!
