Just need someone or someone's to listen lol

So me and my SO have been throwing around the idea of actually trying for a little one recently but I always chicken out of actually stopping my BC.... well here lately like past week or two I can't keep any big meal down for very long, my moods are all over the charts, and when we were most active is when I was most fertile. I want one at same time I'm so scared of being a terrible parent :( and failing my child. I'm testing Thursday or Friday of this week so... guess this was more to vent then anything. Thanks for listening, you guys are amazing.
