I'm in my fifth week of pregnancy. Yesterday I felt like I overdid it a bit on exerting myself; was a bit crampy in my abdomen. I've been having a bit of spotting ever since the positive pregnancy test, last night the spotting got a little heavier. Today my abdomen is still sore, but not crampy, and the spotting is still a little heavier. There was also some red in it, not just the reddish-brown it has been. I'm TERRIFIED that something is wrong and I'm losing the baby. I'm waiting for my doctor's office to open and then I am going to call and find out if they think I should head to the ER. Please send me good thoughts, prayers, vibes, etc. that this is going to turn out to be nothing to worry about. We want this baby so much.
