Ttc baby #2

Brittany
Hello everyone I'm 22 my partner and I have been together 6 years and have a 2 year old daughter. We are currently ttc baby #2 I took an ovulation kit after my cycle this month it showed my surge to be on the 21st into the 22nd we had intercourse on the 19th and 22nd. It is now the 25 and my nipples are tender? My breasts are usually tender around my cycle. Could this be from ovulation? I'm unsure as to what to look for this is are first time actually trying are daughter was a surprise. I don't want to trick myself into thinking I am and actually not be. Thank you in advance for any advice :)
