Cramping 2dpo

Hey so I've been using bc for the last three months then i ran out during this pandemic and my bf and I had sex I assumed already it was unprotected cause I dobt have anymore bc packets I can take and I was sick with a common cold so I didnt leave the house in time to get a new dose. Now I'm worried that I could be pregnant. I definetly ovulated the 27th of march and we had sex the friday before and then again multiple sessions on the 26th. Were still fairly new with eachother and I'm worried I could be pregnant. I dont believe in abortion for this particular situation cause I'm perfectly healthy and have a job and I'm working to be at another job soon with this pandemic. so that's no question. I just need some advice on how to break it to him if I am and also are these symptoms(headache, cramping, fatigue, nauseous, dizziness, insomnia) of early pregnancy it's been a while since I've been pregnant ?
