Need advice

TTC #1 💍

Not sure where I stand at the moment so 4 days ago I had a massive surprise I finally got a positive test and it was multiple brands of tests I’ve had 3 days of really good faint positives and then today my tests are next to negative I haven’t started to bleed yet but my period wasn’t due until tomorrow I’m devastated and not sure what to do or even think or what my next steps should be

I’ve included pictures of my tests the two tests together are the first ones I done and the single one is more recent about 24hrs ago and they todays tests look negative
