Hello Dr, I Am Undergoing Fertility Treatments Since 4 Yrs.

Hello Dr,
I am undergoing fertility treatments since 4 yrs.
I have been diagonised with blocked fallopian tubes at both sides .I have undergone AKT3 course for duration of 6 months prior to proceeding with IVF.I have undergone 4 fresh and 2 frozen transfer cycles.I could concieve 2 yrs earlier with 1 fresh cycle but resulted in missed abortion after 2 months.
Since then I have undergone 2 fresh and 2 frozen cycles which did not succeed.
Recently my Dr tested my endometrial lining for blood flow.My blood flow to uterus is low as per diagnosis.Earlier I could reach lining of 9mm with lupride on day2, Lynoral 0.05,Sildenafil vaginally twice,consevel,Ovaries and Noxis twice daily.But recently since last 3 cycles my lining is not growing appropriately.This cycle I am subscribed to take fertisure,lynoral 0.05 once,ovaries,Noxis and Ecosprin 75. My day 21 reading for lining was 7.8 mm which still does not seem to be at par to have endometrial transfer.Is there anything taht I should try apart from medicines whcih could help improvise blood flow and lining part from exercise which I already follow.
