Progesterone and hCG levels early pregnancy after ivf?
Ok: Most ivf clinics only measure HCG levels approximately 9 days after a day 5 embryo transfer.

If serum beta hCG test is positive that means that pregnancy exists in the body.....But is it necessary to have surgery if we don't want this chils?
Abortion?: I presume you are asking what your options are in case of undesired early pregnancy. If you are less than 7 weeks along, medical abortion is possible with safety and convenience, although hemorrhage is still possible especially if you have fibroids, or your dates are further along than you think. If you are over 7 weeks, dilatation and curettage is warranted. Talk to your gynecologist! ...Read more

What is the best time to take a Quantitative Serum Beta HCG test?
3 wks after sex: There is no need to rush. A pregnancy test gives a reliable result 3 weeks after sex (3 wks after when conception might have occurred), or 1 week after missing a period. If done sooner, a positive result is likely real, but a negative result may be due to testing too soon, and thus lead to a repeat test. If a woman gets her normal regular period, then she is not pregnant, and a test isn't needed. ...Read more

No: If you are PG you are PG somewhere, hopeful intrauterine. The embryo and the placenta create the chemicals that are tested for so if the hug is + you are PG. If not, you most probable are not.

Had unprotected sex on 21 Feb,got last period on 5 Feb. pregnancy test kits as tested on 18 March negative. Blood test beta HCG <1.20mIU. Pregnant?
No: Based on the information you provided, you are not pregnant. It would be prudent to repeat the home pregnancy test in a week, unless you get a period by then. Conception, as defined by the generation of a fertilized ovum, occurs within day or so of the sex. However, it takes about 2-3 weeks for the embryo to make enough HCG to produce a positive pregnancy test. Blood test may be done a day after a missed period. Home pregnancy tests should be done 4-5 days after the missed period. If the result is negative repeat the test in 4-5 days. Use first morning urine and follow instructions for the test carefully. If you do not wish to be pregnant, use contraception all the time, every time. You may consider implanted contraceptive, or IUD. Practice safe sex. Get HPV vaccine. ...Read more

Lmp 4/8/15, took pregnancy test on 5/11, passed a couple clots on 5/12 with abdominal and lower back pain. Beta hcg quant done on 5/15...level 48. ?
See OB ASAP: See OB. You maybe miscarried or you may have a non viable pregnancy or simply first trimester bleeding. The way to find out is to have an OB perform a transvaginal ultrasound. If there are fetal heart tones, then close follow up is needed. Do not go on any long trips or travel by air or out of a metro area where health care is accessible in case you do miscarry and bleed heavily. ...Read more

It is possible that: you were pregnant and now you are not. A quanitative HCG test should be able to give you an exact answer. You might need to have it done more than once.
