I had a miscarriage in April 2023..it was a type of chemical pregnancy.My pregnancy tests were positive but as soon as I missed my first period j did the test and it was positive but within 4-5days I started bleeding.So it was a kind of chemical pregnancy.But till now i have not concieved after that .We tried sex usually 4-5times a month during ovulation period according to my menstrual period dates.There might be any underlying cause for it?At that time in April when I concieved my thyroid test and all other blood tests were done..all were normal.I just had deficiency of vit.D.Should I again visit a gynecologist before trying?
