Hi TinaR - I lurk quite often in the TTCMC thread so I know your journey well. I was so thrilled whn I saw you got your BFP! I hope this is a happy and healhty pregnancy after all you have been through you definetly deserve it!
I got lots of cramping and painswhen I was first pregnant, actually I was still getting cramps till bout 20 weeks! My Doc was great and did HCG tests every 2-3 days for me from 4-7 weeks till I had my ultrasounbd with the Obstetrician. Sometimes it is very reassuring thoigh can make things stresful too. Your level sounds fine to me. big hugs and best wishes!
