So confused and emotional

Ladies, here is the deal I am currently cycle day 31 i recieved my trigger shot after letrozole on cycle day 13 all day this Friday I had very very light spotting if I wasnt looking for it I would have never noticed it. Then it stopped last night until today and then this afternoon I had brownish jelly like cm. Has anyone else had this and still got a BFP I feel like it's probably just AF but trying not to lose hope.
