Basically, about 15 minutes ago I went to the bathroom to pee, and when I wiped, the toilet paper had blood on it-not thick enough to be period blood, and it was also bright red. I also noticed an aching that feels like it's in my uterus-the ache is like if I were to hold my pee for a few hours and then finally go, which is not the case tonight, I've been going as soon as I have to. Currently I am on the Low-Ogestrel birth control pill, and I have been regularly taking my pills since I started the prescription in July/August of 2008. The last day of my period was this past Sunday, and I started a new pack of pills on Monday the 28th. I did miss my pill for Wednesday, however I didn't have sex that day, and I had taken all of the other pills on time. I did have sex today before I took my pill. The ache is pretty dull, but it is still there.
This spotting/aching combination has never happened to me before, and my main concern is that I might be pregnant. Google has given me mixed results as to what this might be, so I turn to you, VPers. ANY advice/knowledge/experience you could share is SO appreciated!
