Some of those things work for people and some don't. Sometimes it takes a while of using them for it to work and sometimes they work right away. I used clomid and got pregnant with it on the first cycle. My cycles were about 30 days long but they weren't irregular. We just were not getting pregnant for whatever reason. I was going to try fertilaid but didn't try it since I got the clomid. I have read stories where fertilaid and vitex have worked for others. They're supposed to be good natural alternatives to drugs like clomid and femara. I hope you get your BFP soon.
Have you hear of the OV Watch? that might be something to look into. Especially if you aren't sure when you ovulate. GOOD LUCK
I too am thinking about trying fertilaid, and I have heard more ggod things than bad about vitex (or chasteberr). I used to have extremely irregular cycles. When I first went to my doctor after ttc for almost 2 years, he gave me provera to enduce a period and clomid for CD 3-7 for the following cycle. I became regular with 32 day cycles, and we conceived about the 2nd clomid cycle. I had a mc and we took a break from ttc, and this last year without it, I am still at 32 day cycles. I have an appt (bright and early tmw) to get started on clomid again. Honestly, I cannot wait! Hope this helped, and best of luck.... Baby dust to all!
