So I need some advice ladies?!

So I had sex Feb 14th. I ovulated the 17th and 18th. The 25-27 I spotted but now it quit. I took a test yesterday night just for the heck of it. I can't tell if I see anything or not. Ppl keep telling me it's a indent. But I didn't know how accurate these cheap dollar store tests are. The picture I took is within the amount of time given for the test. I am gonna retest Monday morning. I just want some second opinions. Thank you.
