5.4 weeks

Update: husband and I did the deed last night, I woke up to some light bleeding and now it’s full on. I did have a chemical.

Two days ago I got positive digitals at night and before that faint lines. I tested today and all my strip tests were negative. I had a wonfo test so light that I would say it’s negative. I am so confused on how 2 days ago I got a positive digitals and now I’m getting straight negatives!

I ovulated super late so I’m 16dpo today, I should be getting really strong lines. My lmp was 9/7 and I ovulated on 9/30. I did get blood tests, but I won’t know till Tuesday. Does this sound like a chemical?! I am really at a loss here, any ideas?
