Trigger shot question

YNA • IVF BFP 5/14, MMC 7/14 FET BFP 11/14 DS1 7/15 FET BFP 6/16 DS2 2/17 FET BFN 11/18, FET BFN 2/19 FET BFP 4/19, baby girl due 12/19
I had my trigger shot 15 days ago and 12 dpo bloodwork hcg was 2.5 so negative.  AF was due yesterday and is no where in sight...  My question is, can the trigger actually lengthen your cycle/luteal period?  I just want my period to come so I can get started with my next cycle!!!
