Spotting

Did anyone have Brown spotting and test and get a BFP? If so, how many days did you test after this? I'm currently 9 days late got Brown spotting late last night only when I wiped, this morning just a tad but more nothing AF usually AF is the worst day 1, but I tested yesterday before spotting occured got BFN and this a.m. with first urine of the day got a BFN. Any responses help...I'm feeling so 😢 I thought this was it. I've been nauseous and fizzy everyday for two weeks now boobs and nipples super sore! Help!?
