Looking for someone who’s had a similar experience

Hey all. So my not so baby boy is now 13 months old. He’s mostly on solids now but still feeds at night. I got my first period back in June and have completely skipped my second period. I know breastfeeding still can throw it off track a little but I’ve had all the cramping and symptoms of if coming for a week now. My husband and I did do the deed 14 days ago so I’ve taken a couple pregnancy test which all appear negative. I’m wondering if I could still be pregnant if I haven’t gotten a bfp yet? Thank you in advance!
