Before 19 Years Later

The Reason Why

Harry P.O.V.
It had been a week since Ginny got 'pregnant'. She was sick all the time, for some reason the potion didn't seem to work on her. I asked Ron if it worked for Hermione and he said she had only had morning sickness once since the class as far as he was aware.
I was jerked out of my thoughts as Ginny got up from next to me and ran out of the Transfiguration room. McGonagoll stopped what she was saying to follow her with her eyes. She then looked over to me and silently gave me the permission I was asking for to follow Ginny.
I jumped up and ran to the nearest girls lavatory not caring about rules. If need be, I would deal with the consequences later. I heard retching from the stall farthest from the door and was surprised she could make it that far. I went over to the door and tried to push it open, it was locked. Thankful that my wand was still in my pocket I pointed it at the lock and said "alohamora". The door opened slowly and I quickly stashed my wand away. I pulled a hair tie out of my pocket and tied her hair back. I had recently learned it was always best to keep one with you in case your pregnant girlfriend didn't have one. I sat behind her and let her lean into my chest when she was done bringing breakfast back up.
I summoned a cup and filled it with water for her to get the taste out of her mouth.
It took me a second to realize she was crying I pulled her into a hug and she sobbed against me. It hurt me to see her in pain that I couldn't do anything about. I gently stroked her hair and kissed her head, muttering sweet nothings into her ear until she calmed down. I heard her voice but I couldn't quite make out what she was saying,
"Ginny. Baby I can't understand what you're saying." I explain as sweetly at I could.
"I don't understand! Why won't the bloody potion work for me? I asked everyone and even Astoria said it worked for her!" She cried sitting up to look me in the eyes. She suddenly got and angry look in her ocean blue orbs. "This is all your fault! It's your genes that are making this potion reject me!" She screeched.
I suddenly remembered what Professor Kellner said in the secret Dads-To-Be class she held a few days ago. Her exact word rang in my head, "Your ladies will have something called mood swings. They will be super happy one moment and the next moment have the attitude to kill. But you must remember to stay calm and most importantly do not under any circumstances go back at her. Just try to calm her down and sooth her." I took her advice now and did exactly that.
"I promise you, my love, it isn't me. Maybe something went wrong with that specific potion when it was brewed. Do you want to go see Madam Pomfrey?" She looked at me an her eyes softened immediately and she nodded. I gently picked her up and started to carry her to the infirmary. She giggled, "Harry you do know I can walk right?"
"I do. But I want to make sure the mother to my child is safe and comfortable. I know I can protect you so I'm going to carry you." I said.
She looked at me with so much love in her eyes and kissed me nearly knocking me off my feet and making me drop her. I set her down on her feet and deepened the kiss. When we pulled away she decided to skip ahead nausea seemingly not affecting her anymore. I smiled and ran after her.
When we neared the infirmary she slowed down and leaned against the wall panting. I was confused until I remembered that Kellner said that the pregnancy would make them get real tired really fast. After she caught her breath we went in.
I instructed her to lay on one of the beds while I went to get Madam Pomfrey. When I knocked her door she came out all panicked and flustered a moment later. When she saw it was me and that Ginny was conscious, she calmed down a bit.
"What seems to be the problem Mr. Potter?"she asked in her stern but concerned tone.
"Well the potion that Ginny was given to ease off the nausea won't work on her like it does with everyone else. I brought her here thinking that maybe you could do a quick look to see what's wrong."
"Ok... Ms. Weasley will you lie on your back please and lift up your shirt."
She did as she was told and look at the older witch expectantly. The Healer of Hogwarts waved her wand in a weird way and muttered a few things. Ginny's stomach glowed a baby blue color and I watched intently, hoping it wasn't bad. Madam Pomfrey's eyes widened and Ginny and I became panicked.
"Well, what's wrong?" I asked incredibly worried. Madam Pomfrey turned to look at me with and expression on her face I couldn't quite understand.
"Well Mr. Potter, it seems your girlfriend is actually pregnant."
