CD 49

Ki
I'm on cd 49, usually I have a 29 day cycle. I've spotted a few times since O but nothing recent (spotting on 9dpo, 12, 15 and 18). My question is would it be dumb to test right now? I just used the bathroom an hour ago but I go all the time lately. I either have a uti or I'm just crazy. 
I have a CB digital but I'm scared to see "not pregnant". I used a couple traditional tests last week, BFN (one with a possible second line).
 Thanks for any support! Baby dust to you all. 👶🏻
