Please, please give me some advice or input. It's killing me.
Here's my situation.
I've been on birth control (TriNessa) for 4 years now. It's always been normal. My period has always started on the 3rd or 4th placebo pill day and lasted for about 6 days. Always.
This past month, I've been having menstrual like cramps, so I had a pelvic ultrasound. I think they were checking for cysts. It came back negative. The next day I had some spotting. I know this can be common with a transvaginal ultrasound. However, the 'spotting' started on a Thursday (which would have been exactly 5 days before my period usually starts), and I still have it today which is Sunday. It's been super light to the point where I could pretty much get by with a pantyliner. Sometimes it's brown discharge, other times it's just very light pink. Twice it's been just a bit redder, but not too much more.
I'm afraid that I might be pregnant and that this could be implantation bleeding? Otherwise, my period just started a week early, which in itself is kind of scary. Could my birth control be starting to become less effective?
Any advice? Anyone ever have a situation like this?
1. This is the first period I had since I quit smoking.
2. I had accidentally skipped a pill here and there. I hadn’t previous done that.
