Please help! Pregnant?

When I woke up yesterday morning, I had major diarrhea. Haven’t had that since the last time I had the flu. Yesterday I went to the gym and worked out. I usually feel a little bit nauseated but never actually throw up. Yesterday was the first time I threw up after working out at the gym. I had some breakfast 45 minutes before going. Came home and was still a bit nauseated but was able to keep some food down. Then I started to get a major headache.

This morning I woke up and had diarrhea again (went to the bathroom twice this morning since I’ve been up), feel super dizzy and nauseated. I just don’t feel like myself.

I supposedly ovulated on the 23rd but I think it’s off by a couple days so I think I ovulated on the 25th or 26th. Has anyone else had these symptoms and found out they were pregnant?
