Well, it happened to me. I got pregnant the first time we tried (with baby number 2.) I took a hpt a day before my period was late, very bright red lines. Saw reg. doctor, who confirmed with a urine test and referred me to the Ob/gyn office I'd used before. I made an appointment to be seen at 8 weeks for initial appmt and ultrasound. At 5 weeks, on a Saturday,I had a sudden, serious cramping incident. Only about 10 minutes, but, like labor pains. When it passed, I had a few swipes of red blood, and a few drops on my underwear. I only had a few swipes of brown blood the rest of the day. Called OB, he said it was too early to check on ultrasound at the hospital, it was most likely a miscarriage, due to my 39+ years (although, to be fair, he said it very nicely, and said it could be Ok, but that the odds were not in my favor.)- had me come in on Monday for ultrasound.
Went in for the ultrasound. The US tech was not too happy, the sac was empty, no fetal pole (now I know from this site that it was very likely too early to see anything!) and the sac was sized at 9 weeks. They had no explanation for that. The doc who was available to see me took blood, and had me come back in two days for more blood. He said it didn't look good, but, sometimes strange things happened. I said, "Oh, you mean there is a chance for this pregnancy (I didn't know about all these stories at the time) and he said, "yes, but a slim one."
My levels were 39,000 and then about 60,000. My OB called and said it was still not looking good. I asked about my retroverted uterous, and he said "no, no, that 's just not true." I told him about so many women on this site. He wasn't buying it. He wanted to see me in 10 days.
Well, today was that visit. Saw and heard heartbeat, baby is exactly right in age to my calculations. I asked about the 9 weeks sac, they said, "forget about it." No answers about the blood and cramping, but, I guess I've learned that that doesn't mean a terrible outcome either.
I have a scar or something in my uterous (they noticed in last time I was pregnant and had an expert look at it)- it's probably from a fibroid I had removed 6 years ago. The tech said it looks like a pocket in my uterous. She suggested that because of my "unusual uterus" that may have been the problem when they looked at 5 weeks.
Well, hope this story helps someone else. This site helped me stay focused on possibility of everything being OK. Elizabeth
