I had a similar situation 2 years back. Pls visit a doctor ASAP, the doctor should do a scan to check if there’s gestational sac and also arrange for a blood test to check your HCG level. If the HCG level is high and gestational sac is not found, it is most probably a chemical pregnancy..
Best to see a gynae ASAP. Try to call KKH central appt tomorrow morning and let them know your condition and emphasise to them you are suspecting sight of bleeding, see if they can arrange any early for you. Otherwise walk-in to their A&E if no slot..
when i was trying to get pregnant with my first child i had a few of these. Turns out i had false positives. Best go poly n take the test if ur pregnant by now they would be able to detect.
Better to check with doctor soon. As you have positive and negative results and bleeding.
Better to check with ur gynae
see gyane or retest again
please see a doctor asap
