Could i be pregnant??? Opinions please!

Ruah • Finally preggers with my rainbow baby🚼 baby dust to all you ladies!!!
36 ttc#1 after loss... I started my natural MC 9/02 and I was only 6 weeks along... Wednesday will be 4 weeks from the day... I have been BDing every other day since MC ended! My cycle was very regular before I got pregnant and since I wasn't that far along I was told it should go back to normal pretty quickly, so AF should be due in the next week sometime and usually my breasts are pretty sore right now wether I'm getting AF or pregnant. Ive been having light cramps on and off like I did when I got pregnant before, no other symptoms really... My boobs aren't sore yet... ! Tested this morning... BFN... but I know it's too soon to test! Could I be pregnant? Opinions please... Ty in advance! Baby dust all around!!!
