I know that we have all tried so hard for BFP and every time that there is any sign that it might be we have to go pee on a stick.  Every time I pee on a stick, I get AF a couple hours later.  I bought the OPK strips and they came with 10 HPTs.  I had an HSG last month and I was told that my one remaining tube was blocked.  I was sad about this so we didn't even try.  I know that we did BD many times over the past month, but I don't know when or if it was close to ovulation.  I am going back to the RE on May 21st for a consult on starting IVF.  I am supposed to start my BCPs when AF shows up.  
Now to today... I am spotting and I have been spotting for 3 days.  This is so weird for me.  It has never happened in the past.  I am driving myself crazy.  Other than the spotting I have no symptoms that AF is going to show up, but it is due to start today.

Re: 3 days of spotting... When should I test?
Trying to have baby #1 since April 2013
DH SA March,May 2014 - Low motility and shape issues. On vitamins per RE to help
Me testing April 3, 2014 - FSH and LH good, HSG showed blocked right tube
April 29, 2014 - First RE appt., right tube needs to be removed and possibly left also if
it's bad too. RE suggests going straight to IVF
June 4, 2014 - LAP/HSC and unexpected endo. removed but tubes got to stay!
June 13, 2014 - Post-Op appointment. We decide where to go next since main issue
is MFI influenced. Trying naturally until decision... Repeat SA in September. Aiming for IUI #1 November 2014.
