#AskTheExpert Hi doctor, I am in my 24th week now and the baby and I are doing well. Had 3 scans so far, the dating and heart beat scan, NT scan and anomaly scan. The reports have been good so far, except on the NT scan I was told that I have high blood pressure on my uterine wall for which I am taking Aspirin 75mg. When do I stop this and is it necessary for me take fetal echo scan or can I skip to the growth scan? And I had taken my first dose of TT during 12 weeks, when is the right time to take the second dose?
