Help me please 🥺

Okay ladies so i had a period from April 28th until the 3rd . And then a period from may 11th to the 15th, and than. from the 27th to may 2nd. Nothing at the end of June like it was supposed to but came july 1st and ended at the 3rd day making that only 3 days and it was really light & pink blood .. after the 3rd day only seen very little light pink spotting here and there for two days after could this mean I'm pregnant since it was there for 3 days and gone right away , also been bding almost everyday and it's hard to predict ovulation since these seem irregular tia i did take pregnancy test yesterday and came back negative, ETA: I've felt nauseous yesterday evening and today I'm feeling a tingling sensation in my breast and light cramping on and off So not sure here ( ALSO my period was supposed to be June 24th until the 28th( predicted glow ) never showed up until july 1st.
