Could i be pregnant? Did you show any signs of early pregnancy?

My period is 3 days late and i just have a weird feeling that im pregnant. Iv been experiencing “pms” symptoms for the past 4 ish days. Today, i did experience cramping for a few minutes. My breasts feel very full. My body feels plump and full (im not fat and i hardly ever feel like this). My belly was a bit bloated earlier. I came to lie down and i fell asleep and ended up taking a deep dreaming nap even though i was fully rested this morning. I just feel very fatigued. I had unprotected sex for the past 2 weeks (the week before was my period and i didn’t have sex) my ovulation week being the first week. What were some of the signs that you ladies were pregnant? I just always get a little bit paranoid
