This is only my 2nd month ttc and I have been reading these post and suggestions women give to increase your chances. I have a couple of ?'s. First I have been taking robutussin for 5 days and I definetly see a change in CM, also been drinking lots of water for the past 2 weeks, my ? is I did an opt test and it can back positive Sat. do I need to still take robutussin now? Also I read from one post that just because it comes back positive it doesn't mean you definetly ovulated. Is this true? Also since it came back pos. and i will ovulate in 24-48 hours I had sex sat. should I wait until Monday to have sex again or should I go for it again today? I definetly want to increase my chances so any advice would be greatly apprecitiated. Thanks
