Did I have a miscarriage? I had sex with my ex boyfriend two days in a row on a Monday and Tuesday and we used condoms both times.Wednesday I was bleeding a little and I took a plan b pill that Same day. Thursday I started having abdominal pains. Friday I had abdominal pains but after I ate certain foods I felt a little nauseated.. That night I woke up and I felt something Pop inside me and I didn't know what it was. Then Saturday it was like it switched up from abdominal pain to lower back pain to being nauseous. Around twelve I felt a very sharp pain in my lower right abdominal and a little close to my hip that was so painful I was tilting over. I went through the rest of the day and I decided that night to take a bath. As I was sitting in the tub and I was about to get out I noticed something red floating around the tub and I got a towel and got it to see what it was because I though maybe it was a cloth but it felt weird and a little squishy. I think I may have miscarried and didn't know it. Blood there was no blood.is it possible that I miscarried? I am still having pregnancy symptoms.

That would be something to see a doctor about, though I have never heard of pregnancy within a week of sex, nor a miscarriage being possible so soon. Reaction to the pill you took, maybe, but without a better history, or an examination, who can say for sure what you are experiencing.

Sounds like Plan B brought out a large clump of menstrual tissue. Whether or not there was a fertilized egg the size of a grain of rice is anybody's guess. I doubt it. Monday to Saturday?
You don't say when your period was due.
You can't really talk about 'pregnancy symptoms.' They are just like menstrual symptoms at the beginning.
Plan B is a real DRUG, remember, not to be used as a back up for condoms.
How about the pill?

Even I can not understand this problems and please take a appointment with your doctor as soon as possible .
