Letdown feeling in boobs

Hi. My boobs have been feeling different sensations than just sore. There have been a couple times it felt I was almost going to let down. I actually had a couple drops I could still get out before TTC (stop breastfeeding last year) and my OB had me have bloodwork before she gave me the ok to TTC which was normal. I have had symptoms and a lot of cramping (mild) since O although it’s not as noticeable. Also am more constipated (sorry) but could be prenatals. Before I tested I could have sworn I was pregnant.

I’m 9dpo and bfns. My BBT chart had a dip 5dpo. Does it sound like I could be pregnant still?
