I am 21 weeks and 1 day my husband and I have our anatomy scan on Monday but only my mom and his mom r gonna be told what the sex is we won’t find out until February 17th. My husband and my mom and my husbands mother seem to think we r having a boy. When I have gone in for the heart beat appointments the heart beat was 160. I know girl and boys heart beats r different I didn’t know if some of u could tell me what ur son or daughter’s hear beats were. This is me at 21 weeks exactly yesterday.
