IB or af???? 4 days late

so I have been having very small amounts of this for the last 4 days. maybe once or twice a day. I had some watery light pink after wiping when using the bathroom after we dtd. I'm 4 days late for af. bloated, I was crampy for about 2 days. is this a sign of pregnancy? all hpt have been negative except for maybe the one from today. can't really tell.

this cm is like ewcm. it's extremely elasticized. any ideas?

glow says I o'd on the 16th of May. period was due 4 days ago. I'm so confused.
