Help me :(

[Jessie2341]

My issue is strange,  I have been to the doctor and had general tests done and I have come back everything at healthy levels however I have felt very sick for a while. I never had an STD test and the last time I had sex was about a year ago when me and my partner of 5 years broke up. I have only ever slept with one person, however I did break up with him for cheating. For the last month or two I have had slight green discharge and whenever I thought to go doctors it would clear up and kept returning etc I work a lot and very busy however just before my period I had a large amount of this discharge and then got my period and it felt as if I had been hit by a car , my body went numb with pain and this period is the most painful thing I have experienced and I have a high pain tolerance. I have had issues with my joints in one leg also not sure if thats related I'm only 25. What worries me is could this be an STD but showing a long time after? All websites say it shows within 14 days and now I'm extremely worried as I can't get to a doctor any time soon.  The discharge is very thick and changes to a almost fluro green/yellow. :(

You have to make time to see your Dr. If this an STD it can cause all sorts of problems like infertily, pain, like you're already having, and if you get a new partner it can be passed on to them.
Please make an appointment as soon as you can, even if it's on your lunch break or something like that.

Herpes is one of the disease which can pass through skin without intercourse. Its symptoms remain dormant for a long time and may abruptly erupt. There can be carrier without symptoms.I do not think your symptoms matches herpes.However it is better to check up to on safer side.Posting in std forum may get you better answer.
