Pregnancy symptoms?

So I know that the only for sure way to know if you are pregnant is if you miss your period and take a test. I’m just wondering if anyone else has experienced these symptoms. I have painful ovulation and sometimes I have PMS like symptoms. But it’s usually one or two symptoms and doesn’t last. I have been nauseous, tender nipples, and tired (more then usual) this past week. I think I may have ovulated early, but it doesn’t seem like the time line adds up. Has anyone else had symptoms like this or input?
