I understand your concern. Bleeding in early pregnancy can be due to- -A normal thing around expected day of menses . Due to implantation, It usually lasts for 1-3 days is scanty. - Hormone deficiency in early pregnancy results in bleeding. Which can turn in abortion. - sometimes bleeding along with pain in either side of midline in abdomen, may suggest ectopic pregnancy, - chemical pregnancy blighted ovum usually starts bleeding get aborted. So when the bleeding is with symptoms like cramping increasing in quantity day by day spotting exceeds 2-3 days. Its advisable to get a full pregnancy check up along with USG abdomen repeated Chat Doctor level estimations to come to a definite conclusion about the cause. At 3 weeks pregnancy can not be noted in USG .so normal practice is to start with progesterone supplements bed rest. Followed by USG at 5 weeks decide about continuation of the hormone. Thanks.
