Hi, just looking for advice. So I've just had sex with my boyfriend and although we did use a condom for the end, he didn't ejaculate in me, we only put the condom on half way through the act. I'm worried that I might need plan B because according to my app (that I only vaguely trust) I'm in prime fertile zone 🙈 I'm worried I'll get pregnant via precum 🙈 there was also a lot of cervical mucus and cramps afterwards too - both I experienced when I got caught out with my son 🙈 advice please!
