I'm 8 weeks pregnant and I had to get tests at 6 weeks, everything came back clear besides chlamydia. Not sure how long I've had it. My partner and I took the 2x 500mg tablets at about 5pm and then ate dinner. My partner is fine besides a little abdominal pain, me on the other hand has been getting terrible sickness lately due to pregnancy and about an hour after taking the tablets I vomited, a lot more than I have since being pregnant. I'm really worried that I would have thrown up the pills and they won't work. Can anyone help me please?
