No period; negative tests

Had unprotected sex 06/29, 07/14, 07/20, 07/27. No birth control methods used.

I have not had a period since 06/07.

My cycle is pretty regular. It’s never been thrown off before. Not since before I had my son three years ago. And definitely not this much.

I’ve taken a few pregnancy tests. If I got pregnant 06/29, the tests would be positive, but is it two early to know right now with the other dates? I’m extremely confused and having a hard time waiting. I was thinking about making a doctors appointment tomorrow.

With my first pregnancy, I tested positive for the first time at 3 weeks.

My throat is sore which happened with my first pregnancy but that was a miscarriage. But I didn’t have any other symptoms with my other two pregnancies.

I’m getting nauseous randomly the last few days. Cold sweats and dizziness today. I was wearing a sports bra to work out earlier and it was so itchy and hot and uncomfortable.

Any thoughts?
