Looks like it's my turn to have bleeding. I am kinda scared cause I have never had this before with any of my pregnancies. I woke up this morning and had a gush of brown blood and some tissue into the toilet. It seems to have stopped now but I am still pretty freaked out. I am going in to see the doctor at 11:30 so I'll keep everyone posted. Hopefully it turns out to be nothing serious!
Had my appointment; the doctor did an u/s and everything looked fine with the baby. The doctor said he had no idea why there was bleeding, but he didn't seem to think there was anything to worry about. He just said to rest and don't do any heavy lifting for the next week. Somewhat reassuring that everything is ok with the baby, but I am still a bit concerned since they don't know what caused it. I hope this is just a one-time weird thing and it doesn't happen again.
Thanks everybody for all your support and all the thoughtful messages.
