Hi I'm A Woman In Her Late 20s. I'm In

Hi
I'm a woman in her late 20s. I'm in a long term relationship , but my partner and I had an abortion at the end of July this year(for personal reasons) pretty much a month after I became ill with flu like symptoms, however since then I have had a continuous sore throat- almost 2 months now. I am also extremely tired all the time, have no energy. My skin is constantly itchy all over, my knee joints ache.in the last few days I have developed a red bumpy rash around my groin area(near knicker line- dosent always itch) Generally feeling of being down & low.
I drank a bottle of wine on Saturday night and since then my sore throat has got much worse and my tounge feels slightly swollen and my chest feels tight.
I even took a pregnancy test a couple of weeks ago but it obviously came up negative (I now have the implant) I'm really becoming quite anxious. I have never had a continuous sore throat like this. I am starting to worry that I may have caught something from the proceedure!
Advice/ help would be very appreciated!
Many thanks!!
