It had happened before, and maybe telling Ernie would ease him more a little bit, that this wasn't really an isolated incident. Though the last time, there was zero chance she could be pregnant. "Do you remember when I was in the infirmary for a couple days, during the OWLs? I was meant to return to class the next day but, I had missed my cycle then too." Madam Pomfrey had kept her there, and prevented anyone from seeing her for a couple days because she had been so distraught, and under so much pressure. That's why sheld had the suspicion that's what was happening again.
"It's alright love. It'll just be me explaining things and being examined. You can come with me and wait in the waiting room if you want to? I'd like that, actually." Ernie didn't have to come in, but it would be nice if he were with her. She was so sorry to worry him at all, if that's what she was sensing coming off of him. When he asked his next question though, she smiled a bit.
"I was going to ask you the same thing." Looking at her hands first and then up at him, a soft smile on her face. "A little of both? The timing wouldn't have been great, but I'm sure we would have managed. But I was pretty convinced I was... so the picture I had prepared myself with in my head, a little boy with your dark curls. That picture disappearing ...it did hurt a little." She swallowed hard and wished he was sitting next to her. "What about you? Are you disappointed, Ernie?"
