Testing Out the Trigger Just Got Harder

I have a small stockpile of home pregnancy tests in my bathroom closet and my plan this cycle was to test out my trigger shot. My collection includes some internet test strips, some FRER sticks (results 6 days earlier!!!! is what it exclaims on the box) and one or two CBE digital tests. My problem is that both the internet cheapies and the FRER test for very low levels of hcg and so that makes it harder to test out the trigger. I tried Saturday morning and got a clear positive with the internet strip and then tested again this morning and got another positive. So, I tried a FRER this morning which was negative within the time frame but faintly positive later. It kinda sucks to have to waste tests trying to see a negative. I guess the good news is that if I have a FRER turn positive within the testing time frame later this week I'll know it's a real positive. Let's hope that is what happens. I don't feel pregnant.
