Got a BFP this morning and went to get blood drawn this afternoon. The urine test at the doctor came back negative but the seven (don’t judge me! Lmao 😂🤣😭) I took at home are faint but positive. Then the results for my draw came back at 45. My last period started on 12/29 (thanks Glow!) and my EDD is 10/05. So making me about 4 weeks. I’m trying not to panic of course but as you can tell by the amount of tests I took today, I’m not doing so hot. Lol. Has anyone had levels of hCg this low at this week and been ok?
