😫 bfn???

Currently 20 dpo after a round of clomid and a trigger shot. Had brown spotting for 4 days, but no AF. I'm pretty regular too, but whenever I try a pregnancy test at home, it's a BFN.

I mean I drink a lot of water, but I can't be drinking that much water where I'm still testing negative at 18 dpo, can I?

I'm currently 6 days later for my period now and I know for a fact that I ovulated on February 8th so I'm just at a loss as to what is going on. Of course there are symptoms of pregnancy. There always are, but I've never had a BFP.

I do NOT have PCOS or any other health condition that could delay my period for this long.

Any advice?
