I am a little worried about my hcg levels. This last month my DH and I were not ttc. We decide that I was going to work on loosing some more weight and wait until we moved in to our new home before ttc again. Well I got my bfp. I was 4 weeks 4 days when I got my first beta and they were 128. My OB said that they were on the low side and that she will recheck them next week. Well I ended up getting really sick and went to the ER. I was scared it may be an tubal because I have had 2 back in 2011. Well they check my levels and they were at 642. So it looks like they are doubling. They did a sonogram and said they saw a sac that measured 5 weeks 6 days. I know for a fact I am not that far along because I did my opks so now I am worried about my levels.
