The suspense is killing me

So my dates have all of a sudden changed. AF is now due 6/9 instead of 6/7. Also, it's now saying that my fertile dates started on 5/21, instead of 5/19. We BD on 5/19, 5/23 and 5/24. I've bee nauseous, exhausted, sore breasts. I've been having cramps here and there. However, I do have fibroids and often have cramps prior to my period. I did a first response test today and it was negative.
