Is there any way of finding out if baby is OK without having to wait until 12 weeks for heartbeat? 40 yrs so already high-risk, 4 weeks now. I took 2 immodiums to clear up travellers diarrhoea, 3 days later a sleeping tablet to get through a longhaul flight, 3 days after returning had my wisdom tooth taken out, local anaesthetic, with tooth still throbbing and 4 pregnancy test-kits later & too much web-surfing has freaked me out. its feeling like a long weekend til I can see a doc in the week.
