First Time TTC need a bit of help.

Me and my bf have been together 7 years now, we r only 21. We have never used protection cuz we were both each other’s first and both get tested just Incase every couple months. Anyway, we decided this month we would start trying but last month I had some weird spotting now I’m getting sick after every meal and every time I drink to much. I don’t wanna take a test and find out I’m crazy, but could I really b from last cycle???
