I came off my period on the 24th of last month and me, my partner had unprotected sex twice 2nd of July, I’m on the second day of my ovulation cycle apparently the app is saying but I’ve been feeling so shitty. I’ve been having really bad headaches, barely eating, sore breasts, nausea, diarrhoea as well. I have really weird irregular periods too

I don’t think I’m pregnant but could all this be from my ovulation cycle? Or is there an actual possibility I can be pregnant? I’ve already got a 2 year old so we are trying. Just wanted to hear off anyone else if they’ve had this
