Happy coincidence

Here’s a little backstory my periods have been very irregular after losing my virginity so it was really hard for me to get pregnant but I got pregnant last year during May, it sadly ended up in a miscarriage and I couldn’t get pregnant again until this year in April. We took some time off sex and my periods were slowly becoming regular and boom I was pregnant. Anyways it’s a coincidence how I got pregnant around the same time I did last year
