Hello and welcome to HCM.
Thank you for your query.
In my opinion, a pregnancy
will have to be ruled out. The best thing to rule out a pregnancy would be to use a urine pregnancy test. This should be used 2 weeks from the time of last sexual contact, or during the first or second day of a missed period. An early morning urine sample would yield most accurate results as the urine is most concentrated in the mornings. (i.e. the first time urine is passed).
The possible causes for a discharge could be some kind of an infection. Once pregnancy is ruled out, you will have to visit a doctor for the same, get diagnosed and accordingly treated as an infection will have to undoubtedly be considered.
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.
