Your story sounds very much like mine.
I'm 36 and we had been TTC since 2012 and I hadn't even so much as sniffed a BFP despite diet changes, regular exercise, preseed, conceive plus, primrose oil, grapefruit juice, etc. We went through all of the testing of the fertility clinic and everything was good. We were going to do IUI but it was just too expensive and insurance didn't cover anything. It would be $4,000 just for one cycle which would give us as much of a chance as a young healthy couple TTC (10-20% chance).
In August, about a week before O day, I took a trial pack of a meal shake called Shakeology. It's all natural and is like eating 5 or 6 salads worth of vitamins. I had friends taking it and they were talking about how good they felt with it and I still wanted to lose a few pounds. The trial was four shakes with different flavors. That month, I got a BFP! But at 5 weeks, I had a MC.
We kept trying and again, nothing was happening. I was giving up. I was looking up what it took to adopt. I mean, I had really just about given up.
I also decided I wanted to start back on the meal shake. I had started getting pretty depressed about TTC and thought I'd do diet and exercise before seeing a therapist.
The shake isn't cheap. 30 days worth is about $100 (which they say works out to about $4 a meal but still, the initial investment kinda hurts). I found some unopened on ebay for about $90 and free shipping. A lady had bought it, got pregnant and her OB doctor didn't want her taking it while pregnant (it has a lot of vitamin A and, combined with a prenatal, can be an overdose on Vitamin A. Some OB doctors are fine with it though because the Vitamin A is from beta-carotene which your body won't absorb if you already have enough). It has herbs in it which have been credited with helping TTC.
I ended up getting it in the mail on CD 1 and took once a day. It's not extremely palatable so I would mix fruits, ricotta cheese (makes it taste like cheesecake), etc in it and would just suck it down. Well, that cycle I got my BFP! On 16 DPO, my beta was over 600. On 18DPO, my beta was over 1500!! Two days ago, I went in for an ultrasound and baby is measuring great at 8+2, great interval growth, with a HR of 162 so everything is going well!
I had stopped taking the meal shake a few days after my BFP. I did some online research and I just wasn't sure about some of the herbs since herbs aren't very well regulated and tested. Some of the herbs supposedly help conceive but also may cause miscarriage. Who really knows but I'd rather play it safe.
I don't sell the stuff. I just found it on ebay because I didn't want to deal with the whole beachbody coach and all the riffraff. If you do get some, the chocolate flavor is pretty bad and I love chocolate. Vanilla or strawberry are better. Get fruits and/or ricotta to add to it and that'll help a lot with the flavor. You can also find the little trial pack like I did on ebay so you can figure out what flavor you might like better before spending the $100.
