TTC after birth control

I am 27 with 2 children. My youngest is 5 1/2. We have decided to expand our family! But.... For 4 years I had implanon. The bc that goes inside your arm. After the 4 years were up I switched to paragard. The T shaped device inserted in. After I removed the implanon from my arm I was diagnosed with pseudo tumor cerbri or some call it intracranial hypertension. We do not know if implanon caused it. We can not prove it so it is idiopathic. My paragard was awesome besides the face it kept giving me chronic yeast infections. My dr was more than happy to take it out. So was I lol I removed the paragard in November and immediately start trying. It is now Jan with no luck :( I know not long. I'm in panic mode here. My husband wants a big family and every test is negative. I'm buying ovulation tests and pregnancy test like a crazy person. I have done way to much research! I can't seem to take my mind off the stress and waiting for my next period or not. :( any advice would really be helpful. Thanks
