TTC

Hi everyone!  I have to admit that I don't always understand the abbreviations you use on the site, but I'm sure I'll catch on.  

The hubby and I are TTC and I am lost.  I've been on birth control since I was 16, I am now about to be 26.   I was on Depo for a few years, but have been on the pill for the last few years now and am not sure how this will affect everything.  While on the pill I never have a regular cycle and when I did get my period it was light.  Now that I stopped taking my pill my period is heavy and I have terrible cramps.  

I'm just wondering if anyone can help me figure out what to expect and if it's likely to take a while to get pregnant?  

Thanks in advance for any advice!
