so my friend has sex with her boyfriend all the time and they always use a condom but condoms breaks. well she texted me and said that she's constantly peeing and cramping and felt sick without throwing up and she told me she's a little late in her period. she talked to her boyfriend about it and he keeps saying she's not pregnant. he refuses to talk about it. she can't get a pregnancy test either so i told her i'd get her one but is it nessassary? does this call for a pregnancy test?
