TTC late 20’s..

Hi friends! Just wondering if anyone can relate to these thoughts.. I’ve been with my husband for 6 years. During those 6 years I’ve never been on BC and we didn’t/don’t use protection. He never does the deed during my fertile times but I honestly get so worried that something is wrong with me since I haven’t become preggo by accident.. I feel terrible for thinking/feeling this way but can’t help it. Anyone else?! We are looking to start TTC in October and I’m really excited but also terrified. Baby dust to all 😌
