Early signs??!

J
TTC - I'm 15dpo (I think...last day of ovulation cycle was 15 days ago) 
Lower back pain
Fatigue
Increased gas - sometimes feeling trapped
Felt a pinching feeling in left ovary for a few days, 
Now feel some dull cramping or fullness in lower abdomen often
One morning of nausea 
Mild headaches 
Tugging feeling in ether side
AF due today - no signs yet!
I felt some pain during intercourse yesterday
Hubby and I want to wait until Monday to test because we're having family over this weekend and don't want to have a BFP right before everyone comes! But obviously it's all I can think of! 
Does anyone think this is our month??! Been TTC since February!
