Please help me going mad.

Annette • Just got my bfp with our rainbow baby 🌈
I ovulated on 7th June (this month) and 2 days later my breasts grew massively! I'm 7dpo and just checked my breasts and they are full of white pimples!! I'm very bloated also. Is this a sign of pregnancy? I'm due on 22nd this month! Please help.
