Pregnant again after having twins 5 months ago

Emma • 19 mo twin boys 💙💙 7mo baby boy🤰🏼 baby #4 is a GIRL 🎀 on the way!

So my period was due today and I just had a feeling something was different! I had a dream the other night I was pregnant and then the last few days I’ve had reflux/heartburn! So I did a test today at midday and it was positive on a FRER! So I did another positive again. This evening I still couldn’t believe it and tested on a clear blue and nothing??

Could the frer be wrong? I’m feeling incredibly blessed/overwhelmed!
