i have a 5 week old baby delivered by c section, and used to shave my genital area regular before having him, but havent done since allowing time to heal. Today i went to shave, and noticed what appears to be a noticable blood blister down there, on closer inspection with a mirror i have noticed a further 3 smaller ones too. My partner has also checked and confirmed they look like blood blisters. I didnt shave as i didnt want to catch them and make them bleed. What has caused these ?? will they disappear ?? we have been having intercourse again over the last 2 weeks, and last night was rather a wilder session ... could it be this that has caused them ??
