Awkward but...I used a vibrator last night (didn't turn it on) and ended up with a small air bubble in my vagina. I started cramping and noticed I had bled a little and also had a couple small clear blobs with blood attached to them. Like literally small pknhead sized. Is it possible that I may have been pregnant and did something to lose it? This has never happened before and I'm still cramping though not bleeding from what I can tell and I'm freaking out....I feel like I did something...
