I need some advice

Well last year I had a miscarriage and I had no idea I was even pregnant, literally no clue I'm assuming I was almost 3 months. Well if I had no idea I was pregnant that means I wasn't really having symptoms or they weren't really that noticeable. Recently I found out I was pregnant. 2 months to be exact and I'm having all types of symptoms and I am really going through hell with the nausea and morning sickness. I don't want my bf to think I'm being dramatic considering I didn't even know about the first pregnancy and now I'm going through hell with this one.
