When did you stop testing? Baby #2 on the way!

Got my BFP on 3/24- pretty dark from the day before FRER so I felt great. It darkened all the way on 3/28... then I ran out of tests so I stopped testing. My wondfos (internet cheapies) ran out on Saturday and almost matched the control line. So I felt fine with that! Now I’m dying to test again but I’m holding back. When have you stopped!
