Hello everyone. Please tell me — it's been about 2 months with no period and the test is negative. I thought it might be an ectopic pregnancy or a missed miscarriage; I read on Google and it seems not. I can't get to a doctor because of work. I can't get an ultrasound — quarantine, everything is closed. But I had all the symptoms.
