So, my last period was Feb 25th-March 1st. I started getting a metallic taste I my mouth 2 days ago along with a stuffy nose and headache. I knew it was way too early but decided to take a test anyway and was absolutely shocked when it was a blaring positive! So I took another and that was positive within 15 seconds as well. Going off my CM I believe I ovulated around the 8th. Is it normal to get a positive like this that soon after ovulation?

I used tests from this batch last cycle and they were stark negatives. And even tested one in water today and it was negative so not thinking they are false positive.
