Need some advise my partner and I did some foul play fingering and grinding on each other on the 23 protected with condom slight penetration on lips on my low fertility day .I stopped because I wasn't feeling well . We just have our first child 7 month old not looking to have another anytime soon . I have extreme anxiety aswell to the point where my nerves and body is reacting I'm feeling nauseous and overthinking . my period is due on the 31st and I just can't help thinking what if I'm pregnant. I know it's impossible I inspected the condom little to no precum inside , no holes and not broken plus my husband was very dry . I didn't take a plan b because at the time I didn't see necessary and I didn't want to delay my period

Help I'm I over thinking ???? Ps I'm allergic to my current BC my dr and I researching for better options .
