Madam/sir I missed my periods on 26th October. I took a test on 27th October beta hcg blood test that was negative and after 3 days I again took a test on 30th October that was positive 27.01. My question is I read online that one time beta hcg test is enough to detect pregnancy after missed periods. Why in my case it took 4 more days after missed periods? I got really worried?

Yes, one Beta HCG test after a missed period is usually enough but not always. In some women, HCG rises slowly, especially in early pregnancy. Your first test (on Day 1 of missed period) may have been too early to detect. By Day 4 (Oct 30), HCG reached 27 confirming pregnancy.

Hi, I have been having nausea since 2nd September till today. I have back ache and cramps like period. My last period was from 17th to 20th August with an irregular cycle. The last cycle was 80 days. Could I be pregnant? I had unprotected intercourse from 28th August to 4th September. I took a home test on 7th, 9th and 10th, and it was negative. Please advise. Thanks.

Hi, I got a positive pregnancy test, which I also confirmed with an HCG blood test. In that test, my values were 779 and 1387, taken a day apart. I am having red brown discharge with light cramps. When I went to the doctor, she suggested a hormone injection and Miprogen tablet for two weeks. Will this situation settle or is there any risk of complication? Please suggest.

I took a test 10 days after transferring two 5AA frozen blastocysts. Is there any chance of detecting on the 14th day beta hcg? HCG is scheduled on 1st December.
