20dpo cd34 and no AF 5 days late

Kayla

Hi guys my period is 5 days late yesterday I did a pregnancy test and negative, I have terribly sorry nipples and boobs my areola has increased in size, every now and then have bad lower back pain and slight cramps my cm is creamy. I ovulated on the 3rd did BD 2 days before and on ovulation, experienced slight spotting before and after ovulation that stoped on the 7th. Please help ladies don't know what's going on? Did any other ladies experience this before a BFP ?
