Got my first vvvvvv faint bfp on Friday and a positive Clearblue digital yesterday that said Pregnant 1-2 weeks. Went for blood work today and my levels are only 13 😭😭😭 My doctor wants to retest in 2 weeks...WTF! Looking for anyone who has gone through something similar or has gone on to have a successful pregnancy.
