My uterine dimensions were 74.7 × 22.5 × 37.1 mm in March, 3 days after the end of my 5 day period. In a scan done on 14th June, my uterine dimensions came out to be 81 × 50 × 26 mm, and this scan was taken 1 day before the beginning of my periods. I've been on ovral l for 7 months now. This change is a 66.7% increase in volume. I have taken 2 Bhcg blood tests in 2 months, both negative and 5 upts all on separate days. My last upt was yesterday and it came negative too. I started my period 4 days ago, 1 day earlier than usual, but they are completely normal Is there any chance of pregnancy here? My last pack of ovral l ended on 9th and I start my next on 17th. Is the increased volume of my uterus normal or should I be worried
