Of course you will worry but you are for sure pregnant! :). Ask for a repeat hcg to see if hcg is doubling. Also w multiple m/c usually your first OB appt is sooner than others which is awesome because you get to see your baby on ultrasounds sooner and watch that little bean grow.
Congratulations!
You have no reason to worry.
Just call and make your first appt and make sure to remind or let them know that you have had 3 mc, most women with 3 or more are considered high risk. I'm telling you this to scare you, but just make sure they know. good luck. :)
No reason at all. I found out I was pregnant about 15 DPO and my level was only 48 and now I am 31 weeks. I also have a had a miscarriage before so I can understand your fear. Its not really how high the level is (since it can differ so dramatically from person to person) but rather that the level doubles within 48-72 hours. Congrats on your pregnancy! :)
