I believe conceived on or around 2/28. I haven't missed a period yet, but on a whim I took a pregnancy test and it came out positive...actually I took about 7 and they were all positive! 😳 I went to the doctor last Wednesday my HCG level was 62, so I was right! They had me test again on Saturday level was 88 and I tested again yesterday it was 128. My doctor is telling me that this isn't a good sign and I should consider a dnc. Has anyone ever had a slow increase in the first weeks and then have it begin to double? I feel like it still early possibly 1-2 weeks pregnant. Is there hope for my levels to being to double? I'm getting very worried and scared. Please help!
