Ovidrel 250

I got my trigger shot on 6/19. I am now 10 days past trigger and 9 dpo. Only symptoms I have had recently is tiredness and headaches. I have had some cramps here and there but they went painful more like small pressures. I’ve been testing everyday to see when the ovidrel will be out of my system and today i got a very very faint line. I should be at 13.08 iu HCG. I took a first response today for the first time and also got a light pink line. It was definitely darker than the cheapies I’ve been using. Anyone have any insight?
