Boyfriend away during peak fertility period

Je
Hi, I'm new here! I'm ttc and this is my 2nd cycle.
Glow predicts that my fertile window is from 20-26 May with the peak day being Wednesday 24th on cd14, but judging from previous months I think I'll ovulate earlier around cd12 which is Monday 22nd.
However, my boyfriend will be away for work 22-24, coming back on Wednesday night. 
Do you think there's still a chance we might conceive this cycle? We have been BDing everyday since my period finished and will continue until he leaves, but I'm afraid it won't be enough... 
If only sperm could survive in a little jar for self insemination!! 😜😈
