pregnant again?!

Hey guys! So my SO and I have been having unprotected sex and I've been ovulating this weeks according to my <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">period tracker</a>. I've been feeling nauseous, sleepy, and peeing a lot. I don't have the money to get a test right now but does that sound like early pregnancy signs? I wasn't nauseous with my son
