I was just thinking that you may not want to take echinacea or any other herbal remedy while pregnant. There have not been enough tests to confirm that no harm can come to unborn babies. It's best just to take a prenatal vitamin with folic acid and drink orange juice or eat fruits for your vitamin C rather than take a supplement. I did tons of research before getting pregnant and a cold or flu will not harm your baby, while an herbal supplement possibly could.

There are many websites that discuss ways to check if you are ovulating. After reading about fertile mucus characteristics and monitoring it, I was able to become pregnant after 3 months. My periods ranged from 27-30 days too.

Good luck!
