Mary

I'm almost 6mo pp and i got the IUD on feb 4th my last period was march 24th since monday i started feeling sick to my stomach and i thought it was the coffee i got from dutch bros but still bought like 12 walmart cheapies 😂 the one i took yesterday was negative i took this today and the line showed up at 7mm this are good for up to 10min it looks more pink in person. Only symptoms i have is sick to my stomach and heartburn which i never get only when I'm pregnant could this really be happening
