CD38 & 16dpo what is going on?

I recently had an HGS test on Oct 22nd (which can back that my right tube was slightly blocked) and then started spotting for two days on the 2nd & 3rd of Nov., I am currently 8 days late for AF and 16dpo but I've taken 3 hpt and all negative (which my last test was yesterday the 19th) I'm getting a lil confused I thought maybe from the test it could have unblocked my tube and the spotting could have been implantation bleeding (it was a light pinkish color mixed with creamy discharge) but Im still yet to get a BFP, I was very stressed after I found out that my tube was blocked but that was only for about a week. what do you think the spotting could have been from? and why would I be so late on my period? I've been 3-5days late before but never 8?

How I'm feel: 1) From time to time I get nausea from certian smells or even a stinky dump truck driving by, 2) My boobs are sore which I get 3 days before AF should arrive (but they've been sore for a week now and a lil more intence), 3) I've been very moody (just filp of the handle sometimes) which is not normally me, 4) I've noticed that I dont want to eat my usual foods (they just dont taste good anymore).

Please let me know what you think is going on, I thought the 2ww was hard now this is driving me insane (Idont think I've been stressed about) Just praying everyday that I am infact Preggers and the hpt is just not detecting it

Lots of Babydust to all :)
