Symptoms at 4-5 DPO

Starting on DPO 4-5 I got cramps in my ovary area on both sides. The next morning (right now) I woke up because of the cramps. They are mostly annoying but every once in awhile a few sharp pains. I also threw up a little in my mouth when I woke up and I’m starting to have pelvic cramps. What is going on? I’ve never had this happen before. My husband and I have been TTC for over a year. We had a chemical pregnancy in February and I didn’t have this happen then. Thoughts? Is it too early to be having pregnancy symptoms?

I honestly wasn’t even going to test this month because we were only able to have sex two days before ovulation this cycle.
