I think I may be pregnant and I'm really scared

Alissa
Hi. Me and my boyfriend have been having sex about 1-3 times a week, always using a condom. I was recently ovulating and we had sex (still wearing the condom as always) and I don't think there was any leaking. 
​Currently I've been getting a few symptoms and i just want to ask all of you. 
​I have had a bit of cramping and tender breasts. I've also had huge mood swings just recently. I haven't had spotting but I'm still worried. 
​What do you guys think?
