Chemical pregnancies

Hey all,

So I tend to upload pregnancy tests so I have a record of them, and photos on my phone. Admittedly some have just me having line eyes. But some were very clearly positive that my partner could see the line. So only including those I gathered they were likely chemicals as I had several positives on those occasions.

Going by these since 2017 I've had 5 chemicals and nothing sticks.

Is there anything I can help prevent this? I have started taking conception vitamins but just worried it'll never happen
