I'm back ladies!!!

Hi ladies. Most of you know that I found out I was pregnant 👶🏼 In June but I miscarried in July 😢... my cycles started to regulate itself after the miscarriage and the last two has been at a 24 day cycle when I was previously at a 27 day cycle before the miscarriage. Tomorrow makes me 7 days late based on my normal 24 day cycle. I haven't noticed any obvious changes but one week ago my nipples were really sore and I felt nauseous a couple mornings but nothing out of the ordinary. I usually spot the day before my period (before and after the miscarriage). I haven't seen a sign of my period. Could I be pregnant again or does miscarriages throw cycles off (irregular to steady -back and forth)???
