What’s wrong with me?

Hi I’m just wondering if anyone out there has experienced these issues or heard of something similar...

I was on Evra patch for months and it was going very smooth, loved it.. then I got a stomach bug 5 weeks ago and was prescribed antibiotics..

I kept the evra patch on for 2 weeks continuing without a break and when I removed it I had what would look like a blood clot or even “implantation” period.

It was 2 days only. First day was reddish brown and second day was very light and pink.

Since then I have been vomiting inconsistently and feeling nauseous. My doctor said nothing to worry about that it’s probably gastrointestises ... Ive taken numerous pregnancy tests over these weeks but all come back negative.

I now have constant bloated stomach no matter what I do or don’t eat and with it an UTI...back pain ...

I’m going to my doctor after the weekend but just curious if anyone has experience on what it could be?!

So strange?!!!
