I have been spotting since MONDAY. I had a tiny bit of brown blood on Monday one time and a BFN PG test.
Then Tues. a small amount two times when I wiped.
Then yesterday I wore a tampon and---OMG--I am so sorry this is sooooo graphic---when I took it out after 4 hrs, there was a small, dime sized amount of light brown mucus-y stuff. ICK, I apologize for the TMI!

I didn't use another one and had nothing else for the rest of the day....
Today, a small amount of light pink/brown when I wiped after, ahem, number 2.....but that's it.
I had cramps last night like I was going to start...was fully expecting to wake up in the middle of the night with AF.
I don't think I am PG, I really don't. No symptoms...no sore bbs, no nausea, nothing. Plus, I just don't FEEL pg and I think that intuition is very telling. When I was Pg with my DD, I just FELT it.
But *** is going on. I am 16dpo today. I know this for SURE b/c I had an u/s that confirmed O had happened in the last 12-24 hrs. so I am SURE about my O dates and how many DPO I am.
SO---here is my dilemma--I am supposed to have my HSG on Tues. But if AF is going to start today or tomorrow, I will only be on CD 5 or 6, and am not sure if that's too early for an HSG. I know they want you to not be bleeding.
My RE does them on Tues/Thurs--should I see if I can get on the Thurs schedule instead?
GRRRR. I am half-tempted to ask for a blood test today to see WHAT is going on.
Ideas? Thoughts?
