I’m scared I’m preggo

So my boyfriend finished in me accidentally (I was just too hot for him ;)) 😂

No but in all seriousness I’m on the pill Estelle-35D to be specific and 20 hours later I took plan B. I haven’t missed a pill once but I was meant to get my period today and I haven’t got it. It might come tomorrow but has anyone taken plan B with the pill and had a delayed period?

Please let me know bc I’m starting to panic xx
