fiance is suspicious that I'm not just sick

Seaira

my fiance was released from prison about 3 weeks ago. I think I have food poisoning but he either doesn't think it's that or he's hoping I'm pregnant. he wants more kids I do too but 3 weeks is a little early to tell. i was completely and honestly abstinent the entire time he was gone even tho I had permission to I'm not that type of girl. I just can't bring myself to do that when I am in love with someone. I'm not a cheater so that's out of the question. And I don't think he even doubts that. ok so a rewind I have a daughter with a different relationship she is 3 but while I was pregnant with her I had a period 2 months into it I didn't know til I went to the hospital with kidney stones, well so I thought I had no signs of pregnancy no sickness nothing and I know every pregnancy is different... so back to the present what's supposed to be my ovulation cycle started a few days ago I woke up nauseas and overheated I blamed it on ovulation of course but the next day I was sick still in fertility week.. I'm trying to blame it on the ovulation or I ate something bad but he doesn't think so he says I'm assuming I ate something bad instead of looking at the signs... it's too early to tell right? he has me second guessing this whole sickness
