Hai I am Krithiga
Got married at June 1 2014

Unfortunately Baby got aborted on Day 74 ie on Feb 27 2015
Then i was taking chechups every cycle


And now

I had my period on 03/10/2016 (Day 1)

Had Ovitrop 4 Units injection on menstrual cycle days 3,8,9,10,11,12,13,14,15,16

Moreover I Had very Light Bleeding on Day 17 (19/10/2016),Day 18 (20/10/2016), Day 19 (21/10/2016),Day 20 (22/10/2016)
Just three or four drops each day
My doctor said it might bleed when embryo fixes in the uterus

On Nov 9(Day 38) I got urine pregancy test positive

Had a scan on Nov 16 (Day 45)
The doctor said still baby's heartbeat has not started
And based on Gestational sac size she told that was considered to be DAY 35

SMALL GESTATIONAL SAC SEEN MEASURING 5.0 × 2.0 MM

Again i took home pregnancy test it was positive

My questions are
1. Does gestational sac means indication of start of pregnancy
2. Why does the embryo date varies with my original menstrual cycle days (That is, doctor said to assume 45th day as 35th day only)
3. Is this normal
