Worried

Kala • Wed, Mar 30

Got a positive test the 26th. Went to the hospital for unrelated reasons yesterday they did blood work and said my hcg level is at 52 so i should be 4 weeks. I feel like that's low. Also i had very sore breasts before i got my bfp but now i can barely feel the soreness. I'm worrying myself to death. HELP!!!!
