Hello and welcome to HCM. Thank you for your query. The unpleasant odor and white coloration that you have observed could be signs of a sexually transmitted infection (most probably fungal infection), and will have to be looked into by a gynecologist at the earliest. Sexual intercourse during this period is advised against, as your partner can also be effected. Please abstain from all forms of sexual contact during the treatment period and for at least 7 days after the treatment has been completed as well. About this growth that you have noticed, I wish you would have described this further. Is it similar to a wart) Cauliflower-like? Small? Genital warts are a sign of human papillomavirus (HPV). This will also have to be looked into. The variations in your period and difficulty in conceiving could most probably be because of the infections, these can be treated. And will most certainly have to be treated as they can cause complications to your pregnancy and even otherwise. They can be treated, so why delay this. Please visit your doctor at the earliest and get elaborately examined. I hope I have succeeded in providing the information you were looking for. Please feel free to write back to me for any further clarifications. I would gladly help you. Best wishes.
