Hasn't hit me

Hey everyone. My head is all over the place. I got my first ever positive pregnancy test after years of thinking I was infertile or something. I'm 25, and have been off of birth control since April or May of 2015. Around January 2016, my husband and I decided we wouldn't try but wouldn't prevent. Nothing happened. Every month I would get excited thinking maybe I was pregnant, and every month my period would come like clockwork. A few times it was just a bit late, but mostly regular. I started to have concerns. The pressure started to build after hubby and I got married in August 2017. The only thing everyone cared about was us having a baby. They'd ask when we'd have one not even considering the struggle we might be having behind the scenes. So after a ton of research and trying expensive vitamins, I came across this natural supplement called Vitex. I started taking 2 a day the day after my period started, and BOOM I'm pregnant. It only took one cycle of taking them. The thing is now I'm in shock. I mean I've literally broken down in tears over not being able to conceive and now I'm really actually pregnant. I'm so scared and so excited and absolutely beside myself and feel like I can't even think straight. When will it set in ??
