Losing our mind in the waiting period!!!!

We have not POAS yet - it 10DPO or 7dp3dt so I think it's too soon? We are nutty about it though - starting to wear us down - I am obsessively googling everything. She has a nasty rash and bruises all over her back and bottom from the PIO progesterone oil shots - only 4 more days of those regardless of result. Not sure how much longer we will last without POAS but absolutely paralyzed in fear of a BFN - after 2 years and over a dozen attempts and $25k, we are just READY for this to be our turn...
