tryin to get pregnant

Ra

Me and my boyfriend tried to get pregnant last year and we did not conceive we tried from aug-oct then from dec-march and we are now going to try again. Last time I tried fertileaid all the products- men and women, Geritol, folic acid, opks. But this time I really don't wanna spend alot on supplements since they seems to not help. I have purchased soy isoflavones this time. I've been to doctor but seems to not wanna help. I had been put on birth control in June to help see if that would help buy I quit then mid cycle in July-Aug and started period on day 20 instead 28 days so that put my cycle days to 19 days. Don't know when I will ovulate someone had said you'll ovulate 12-15 after seeing red. But don't know
