Body Dismorphia and Hormomes

I'm fat. I know that. Been overweight since I was 17. At my best I was toned and thick at 220. My worste.... 325. For a VERY long time all I could see was that fat. No curves, no cute dimples, just a fat useless whale. And then he came along. Granted we were both seeing other people and that wasn't an issue, we were very close friends. But as time went on, we felt less connected to our partners and more connected to each other. 4 years later and two years of TTC and we are married and are 2 and a half months pregnant. This beautiful creature that God placed in my path of life has replaced all of those negative nasty and horrible voices and views of myself through these last 4 years. He has tought me how to see myself through his love and his heart. I am still overweight, I am still curvy as all get out and I am me. However... As these hormomes making our child crash through me and change my body, they are reaking havoc on all the hard work we have done. I don't feel sexy, I feel bloated, gassy and sick. I am not horny nor do I chase after sex like we used to several times a week. I feel gross because of the "normal" discharge my vagina is making and I've become very embarrassed during and after sex. He doesn't judge. Ever. He is so excited and reads about everything during and after pregnancy and has assured me time and again how beautiful this process is and how much he cherishes being able to take care of me with the nausea and would never make fun of me wearing a depends after birth of need be. He is literally an angel sent from heaven... But why for the love of all that is holy do I find myself awake late at night crying over my renewed extreme embarrassment of my changing body and worry that with the added bump and weighr of the baby that he would leave me? After 4 years of most everything life could throw at us (deaths to homelessness to drug and alcohol addicted family to financial upa and downs) why would I ever think he would leave? Screw you hormones... that is all.
