6 dpo too early for pregnancy symptoms?

Took clomid 3-7. Scheduled first <a href="https://glowing.com/glow-fertility-program">iui</a> but dr cancelled bc I had 5 mature follicles. Husband and I were together only twice in my fertile week. We didn’t want to press our luck with 5. Anywho..I woke up last night at 2 am to throw up and felt like crap all day. Any thoughts???
