Pregnancy and periods same time!

Nav

Last week i was not feeling well so my husband randomly asked me to check pregnancy and it was positive. But it was too early as i had my periods just 3 weeks ago. So i went to doc and she had me a blood test which said I was 4-5 weeks pregnant!!

I couldn’t understand whts going on. I went to ultrasound next week and she said i was 6 weeks pregnant but no heartbeat yet!!

M woried af coz my first baby had his heartbeat at six weeks.

And those periods i had were heavy periods not just spotting..

Anybody else experienced something similar?
