Early pregnancy test recommendations

Jamie

Hello I have been trying to conceive for almost 2 years we just went through our first IUI with medication over 2 weeks ago I am about 3 days late for my pregnancy but I have taken the pregnancy tests that came with my ovulation kit that I ordered on amazon and it’s a negative ...should i just wait this out or actually get the pricey pregnancy tests from cvs...I am so tired of he disappointment IUI was very stressful.....anyone take the pregnancy tests that come with the the clinical guard ovulation package ....
