Baby advice

I miscarried 3 years ago and was so depressed I didn't want to be around any of my friends with babies. I recently found out I was pregnant but I'm not as excited as I was the first time even though I've made it farther along, my child's father is not excited about the pregnancy , and I believe I'm allergic to the hormones my body is producing because as I was driving to work my throat started to swell closed (something that has only happened when I was on my period before I started bc) What do I do.? Please I need all the advice you have .
