Ovulation

So I had an IUD for 3 years and had it removed in May. I had my first period end of May beginning of June. I took a pregnancy test last week and it was negative (I knew it would be but I would love to be pregnant) but anyways this is my ovulation week and I feel like SHIT! Has anyone else experienced this?!! Every morning I either wake up starving and need to eat NOW or horrendously nauseous. I’m telling myself it’s impossible to be pregnant right now, right? I talked to my big sister and she’s insisting I test again in the morning for pregnancy but can see maybe hormones making me sick.

I’m now in my TWW with a lot of BD during my fertile window. Please help lol, why do I feel like hell?
