Having Bad Cough Since April First Week.

Having cough from first week of April, I went for RTPCR on 11 April but it came to negative and I came.to know that I am 4 weeks  pregnant. As consulted with gyno she told me that it could be your pregnancy symptom not to worry about it. Later my mother comes covid positive with both lumgs involvement and my husband was also positive. My RT PCR still came.negative on 24th April but due to pregnancy Scan and Xrays cannot be performed. At that time doctor also started covid medications for me but only zinc and vitamin c due to pregnancy he avoided antibiotics as my saturation was normal. Now its been 2 months but I am not getting any relief in cough and because of this i also feel abdominal pain. Please suggest
