Hello everyone I am 7 weeks pregnant and I had my first scan yesterday, doctor said report was normal. Baby heartbeat deducted by 132 BPM But still doctor have givene hcg injection 5000 iu to prevent any chance of abortion. Later when I checked online for the injection it says not advisable for pregnant women as it may cause birth anomalies in the child but Dr. has asked me to take for every week till 12  weeks, Is this advisable, please help...
