Need help interpreting blood test results

Hey all,
So my period is now 4 days late, I'm not getting any strong signs of period coming. What i feel as strong cramps always turns out to be gas! Im on cycle day 36 now, and ive had two bfn! One this morning! Dont know what to think or do! 
I got a blood test done on Saturday, which was supposed to be day 3 of my cycle and i got the hormones lh, dheas, and fsh tested. I'm not sure what the results mean now that Saturday was day 34..can anyone help me out?
Lh= 5; dheas=4.9, fsh=2
The lh and fsh levels indicate luteal phase at that time. Not sure what else it means. Is it possible to determine pregnancy based on routine bloodwork?!
I think im clutching at straws now but AF just isnt comin right now! At this point i wish it would just start..so i can move along...😔
Feelig very down..does anyoen have a similar story??
