Pregnancy ?

Kayla • 🎀Grace`s mamma🎀
The start of my last period was June 3rd. According to glow I should start today, haven't had any signs of AF and feeling like I'm pregnant. Sore boobs, nausea, etc. if I were to be pregnant I would be almost 4 weeks pregnant. Would a pregnancy test show positive if I were to take one in the morning????
