😥 I don't understand why its so hard to conceive 😤

I'm lucky not to have any problems other than an irregular period (come on to much) but since I've been taking vitex my periods are back on track I also take geritol and prenatal vitamins but I don't understand why I haven't conceived my second kid yet ,my doctor says i'm good to go for it and my hubby is in great health. For some reason it's not happening I do opks and all that other crap and still nothing. My friend just got pregnant after having cyst an getting and ovary removed i'm so happy for her but sad at the same time because i've been trying much longer and I feel it will never happen im 34 time is ticking 😖
