2 months later still not sure if it was a Chemical pregnancy?

[AB1992]

So I miscarried in April, pretty straight forward I was 6 weeks a long and about 2 weeks later my tests were negative we tried again straight away and I took a test on 7 DPO the next month and had a light positive then on 8dpo I had a pretty obvious positive on one brand of tests but my easy@home tests were negative. The tests with positives are tests the doctors gave me to test my heg after the MC. 9dpo I woke up and tested again with the tests got a positive on and easy@home and they were all negative. My period arrived a day later than usual I usually have an 11/12 day luteal phase that month my period arrived on day 13 and I had brown spotting a few days before which I never have with a period usually. As you can see the tests have a pink line and pics were taken in the timeframe.
But is it possible for tests to go completely negative within 24hrs after a positive? Like positive 8dpo and negative 9dpo??

Did the lines come up straight away as they look quite grey? Getting a positive at 7dpo is pretty impossible as it takes at least 6dpo to implant then a few days for hcg to rise enough to be detected by a test. The tests the drs give aren’t any more sensitive than ones you can buy. I’d trust the easy@home as they’re very reliable. I think you just had bad evaps and your period was just thrown off a bit because of the miscarriage

The ones on the white tests look like indents

Thanks for the reply guys, I don’t think they were indents as I did test the tests with water too to make sure and there was no second line, and the line was pink in person 100%. But who knows ♥️
