What do y’all think?

We haven’t been trying, but we haven’t prevented either. We had sex 2 days before ovulation day so it was my fertile window day. And he did cum in me. And my last period was the 20th of February. I was supposed to get it the 18th of this month, but I’m 8 days late. My period has been regular and a few days after ovulation I was cramping it felt like period cramps. And then when I missed my period my doctor gave me a urin test and it was negative. So here I am 8 days and I’ve taken like 4 test and they are all negative. I’ve been cramping and super gassy. Every little thing has set me off. And I’ve been have diarrhea almost everyday. My face is also breaking out too. What do y’all think? Should I wait 1-2 more weeks to test? I have test strips coming in the mail tomorrow.
