When to test?

So I just got married July 24th, my Husband and I was very careful the first few weeks till after my first period as a married couple. After that we have not used any type of contraceptive. I’m curious if I may be pregnant as we did have sex during my ovulation period without any contraceptive. As of right now I feel some pelvic cramps, sometimes I get a little nauseous out of nowhere (never throw up tho) and I’ve noticed I get out of breath easier. Only sometimes tho..
