There can be observer variation in measuring length of cervix. As long as it is more than 2.5 cm there is nothing to worry. Also if you have not gone into preterm labour before chances are very low unless your pregnancy this time has developed any new complications. You can continue to take susten tablet as advised but there is no evidence to show that bed rest in pregnancy prevents preterm labour.

You can investigate
hsg
harmones
sonography 11 th 13th 15 th day
and as per advise of Dr. Take inj for ovulation.

Your periods are regular with these medicines and now chances are bright that you might conceive. You can try between 12 to 16 days of cycle.

hi lybrate user, as you are 7week's pregnant with light subchorionic bleeding. don't worry you have to take extra precautions for 3months till bleeding stops

please take complete bed rest, start injection Susten 200mg once a week.
start cap Susten for vaginal insertion continue with folic acid.
no sex, lifting weights.

Drink more water
eat more fruits, water melons etc
keep good hygiene.
Avoid pressure on lower abdomen if doing sex. No harm as such just by sex but careful.
Nimbu pani every day
tulsi patte every day
kadhipatta 4-5 leaves everyday.

Now you urself know that these medicined do not work. These are of no use and it has not beed proven to be effective in cases like bleeding during pregnancy. You can stop all these and continue taking only folic acid and keep repeating the scan every week.

if you feel dizziness with susten 200, you can take vaginal preparation of natural progestogens. get your urine culture and sensitivity test and revert back with report

The negative tests mean that you have not conceived.

The period may be delayed as you have been given a high dose of progesterone ( Duphaston and Susten )....so wait for the menses to occur, or meet your Gynec, who may repeat the Urine test or ask for a Beta HCG levels

Beta HCG levels are ok, need your current usg report. If you have been able to conceive with the polyp it should not cause sn abortion, however exact location is not mentioned here, stress on rest, and progestetone supplements

Is IgM positive? then you will have to worry. IgG positive means you are immune to Rubella, which actually is GOOD for you.
