It could be caused by one of several the glands you have around your labia area swelling up, a lot of woman find they come up at different times during the menstrual cycle sometimes big sometimes just small, do you notice any colour change on the skin over them at all?
You can always make an account on here then use a photo hosting site or Dropbox to store the photos and send the link by private message to me if you want to.
I learnt about this just by researching an going by replies from females that have been to the doctor an posted the results of what there's was.
Hope this helps you ☺
If you do keep on getting them and your concerned about it then I would advise a trip to your doctor but I'm sure they will just confirm what I said, if they are away from the sensitive part of your labia majora you could always try using the medicated facial wash that's used to clean skin pours to prevent acne or rubbing alcohol but be careful how close to your labia you use it or it will feel like your on fire down there lol.
Glad to help an if you have any more questions feel free to ask and I'll try to answer them ☺
Yes babygirl you should talk to your mom im a mom of a 16 and 13 yr old and i would want them to talk to me about something like this i know it can seem embarrassing but odds are that your mom has probably experienced the same thing im on this site now myself because iam having the same issue and its always best to let your parent know whats going on with your body as embarrassing as it seems so your mom can keep you healthy and keep your doctor and herself informed on what's happing inside your body and know that whatever is going on with you chances are that your mom and doctor has already been through the same thing or have treated or learned about the issue you body is going through..I hope it helps also im sure its just a ingrown hair or a cyst that is not cancer but sometimes will require a doctor to numb the area and drain the pressure and remove the cyst sac no biggie you do not get put to sleep and u r up and moving around after its done with mild discomfort i hope this helps good luck..n
Mine its tiny.. it gotten smaller i believe. But i don't even know what it is. Showed the doctor and she didn't even seemed concern.
