Newbie - looking for advice

Hey guys was wondering if someone could tell me what might be going on. My period is 5 days late and I got a faint BFP at 2 days late but since then they’ve been negative. At 3 days late I had a negative blood test.

If it’s a chemical pregnancy when can I expect to get my period again?

Is there a chance I could be pregnant? I’m planning to wait until I’m 7 days late then test again

Thanks so much, been searching the feeds to try and find some answers but no luck x
