Late 🤷‍♀️

I posted a little while ago about how my guy and I where having sex, he did have a condom on but as he was pulling out he told me to stay still as the condom was coming off but was still just on him, I’m now a day or two late on my period and have been bloated and slightly nauseous with food for 3 days or so. I think the app is wrong about how I’m having my period this week as I had ovary crap about 4 days ago and (this sounds so odd) but for the last 4 months I have had my period the day of the full moon (it’s a bitch) it’s currently something like 19 days since my last period and last time it was just under 4ish weeks between them, so I think I’m just stressing but do yous think I could be pregnant ? I don’t think I’m due properly till the 14th should I wait till I’m late then to test ? ( I’m 19 I really don’t want a kid and I haven’t gone on the pill or anything else due to it really fucking up my mum when she was younger)

EDIT: hahah woohoo got my period was just stressed 😂😂
