in addition...........
Robitussin is a brand name of a product that is based on guaifenesin, an expectorant. There are other guaifenesin based cough syrups also . It is used while TTC to thin the CM to make it more sperm-friendly. 1-2 tsp. twice daily about six days before suspected ovulation day until the thermal shift. Make sure the product only contains guaifenesin without added decongestants or antihistamines, which could dry your CM.
good luck i hope you'll get BFP soon......
its more like an egg white if ovulation is near...
any ways i've read that robitussin (guaifenesin), you should buy the plain one with no letters after it... robitussin can help loosen up cervical mucus...
hope it helps....
