How long does the shot usually stay in your system? My dr said not to test for 14 days. The first cycle I got the shot I didn't test early and sure enough day 14 AF showed up. Day 12 will be sunday -which is H's bday. I want to test that morning but I'm scared if I get a BFP that it might be false because of the shot. Should I just wait it out until AF should show up?
There is a reason your doctor said to wait so you should do so. The hpt tests for the very hormone you had injected into you. Day 18 is generally more accurate than day 14 anyway, since you have completely missed your period.
