7 dpo intense smell

I’m about 7 dpo ( I didn’t test ovulation this month so not 100% sure) but I took my husband lunch yesterday, steak and potato salad and as soon as he opened it it smelt so bad to me. Like rotten I wanted to puke 🤢 (he said it smelt Normal to him) I’m not a picky person and love these foods usually. We’ll ever since for the past day in a half the only thing I can eat is sweets without wanting to puke. I had 4 bags of kettle popcorn today. 😅 has anyone else had this happen? I’m supposed to go do my hsg test once my period starts but hoping it doesn’t come lol 😂
