Worried about getting pregnant

Hey moms! So pretty much I'm looking for some advice/insight on my current situation. So my husband has been super frisky lately and given that we have an almost seven month old we are usually very careful. Well tonight he was in the mood again but we had run out of condoms, so he just pulled out. Everything was fine until I went to the bathroom later on and there was a wet mark in my panties and upon smelling it, realized it was definitely him. So I go to him worried but he insists that we are fine and doesn't seem worried at all. I am still breastfeeding and have not had a postpartum period yet. I have also been on the mini pill since I had my daughter but will absolutely admit that I'm not the best at taking it at the same time everyday. I understand there is always a chance of getting pregnant, but should I be as worried as I am given the circumstances?! Any help is appreciated TIA 💋
