Unprotected sex 😩😩😩😩😩

Ive been seeing a guy for a few months now, he is just about everything my ex wasn’t, he likes to show me off, he is very affectionate and isn’t afraid to show it and I really dig that stuff considering my ex was abusive, manipulative and narcissistic. We had unprotected sex on Sunday early hours of the morning and I haven’t been able to get to the chemist for the morning after pill and it is now Monday night. I’m freaking out about being pregnant, I already have 2 little girls and he absolutely adores them and has been saying how happy he would be if I was to be pregnant cos he already knows I’d be an awesome mum, but In reality it’s too soon and I haven’t even told my parents/fams I’m seeing somebody. Is it too late to take the morning after pill tomorrow? Tuesday?! I hope not I feel so sick thinking about it and best believe I’ll NEVER have unprotected sex againnn
