Hoping AF doesn't show today.

Kristina • Finally got our miracle baby - now to prevent pregnancy.
This was our 4th cycle trying and well...it's just getting old.  I'm sensitive to those who have been trying a very very long time but I'm sure you can understand my position as well.  
Now I do have signs my AF is coming.  I'm cramps.  If I am going to get it, I hope it's a nice full blown AF.   My last AF was so light I didn't even need a tampon and my OBGYN said that if I'm going to get AF a light period when trying to conceive is not usually a good thing as my lining probably didn't fully shed. 
So here we are the morning of.   I ovulated 5 days sooner than usual which means a shorter cycle this month.  I started getting mildly cramps yesterday into this morning.  I'm aware that period symptoms and pregnancy symptoms are just about the same so I am not going to speculate.  I took a pregnancy test on Friday when Glow told me to, and it was negative.  So I assume probably negative.  I'm NOT going to take any more though unless AF decides not to show!
