Could I be pregnant with these symptoms on 10 dpo?

A: You may be pregnant. A lot of women who are pregnant report similar symptoms shortly before their period comes. And about a week after ovulation you would expect the fertilized egg to implant inside the uterus.
However, these symptoms are also often reported by women who are not pregnant and they are not specific enough to reliably diagnose a pregnancy.
If you want to be sure that you are pregnant, you may want to wait until you miss your period and have a positive urine pregnancy test. If you are pregnant then a sensitive urine pregnancy test may be positive a couple of days before missing a period, but most are not positive until after  you miss your period.
Alternately, you can do a blood pregnancy test which can be positive several days before missing a period.
