What is the effect of pushing SUSTEN200.

Hello!! I am 4 weeks 6 days pregnant. I had two miscarriages in past history. Doctor prescribed to do Endometrial test by blood of myself and semen test. As a result, Problem detect: positive - TB in semen of my husband in high range and positive -  TB has been also in me in very lower range,  Doctor prescribed us medicine to cure that problem. My husband took for 6 months. and I take for  one month. And repeat same test and as a result - TB is negative both of us. We didn't try for 1.5 yrs due to scare of those miscarriages and want back to normal life. Recently, Doctor has done one hydrotubation and prescribed us to try in normal way. I conceive. My last LMP - 12.09.2022. Pregnancy detection in kit - 1. 10/10/2022, 2. 15/10/2022.
