To test or to wait?....

Cheyenne

Currently 7 DPO will be 8 tomorrow. I really want to know if we’ve conceived but at the same time I’m so tired of wasting $$ just to see a bfn. Period isn’t due until the 22 I think. Have had off cycles but got a positive OPK finally this month. Ugh hate waiting! I had planned to test on the 19th. What would you do?....
