Missed periods

Theresa

I have not had my period since late April. So I have technically missed 3 periods. The last one was late, but much less late than this. I have never had sex, but I have made my boyfriend ejaculate and I’m thinking about all the crazy scenarios I might be pregnant because of that even tho I have never undressed. But I feel like I must be pregnant since I have missed so many. I feel so stupid because it’s illogical but I am still so scared and anxious that I am. I have zero symptoms of pregnancy too so it makes no sense. I know periods can be late because of stress and changes in diet and exercise which I have gone through, but this extreme? I’m just really scared and hope I can have some guidance. Thank you for any help
