TTC, need opinions!

So, my husband and I are trying to conceive baby #3! We have been trying roughly 9 months and my period is usually right on, never late. Well my period is now 13 days late and I took a pregnancy test 4 days ago and it came back a BFN, I have been very sleepy and my appetite is a little more than normal. My nipples are sensitive compared to normal. My cervix is high, closed and soft, but today I have had a little pink on the tissue when I wipe. I have been having slight cramps but I really feel pregnant. I have been a little more sensitive to certain smells too. I really want to be pregnant, but I'm wondering if this could be a start to my period? Or if anyone has gone through something similar and was still pregnant.
