First month TTC and lots of pains???

Hi Ladies I also posted this on TTC but thought some of you might be able to help It's my first month TTC so not quite sure what I'm at! (V excited though ) I've been on the pill for around 11 years and came off it last month I have come off the pill before on a few occasions over the years for opperations etc. and have never had any problems and have gone straight back to a 28 day cycle. This time though I'm getting bad pains in my sides and lower tummy like cramps or something all day yesterday and this morning, presuming I am still on a 28 day cycle, this week would be when I should be ov. Are these pains normal? I've never had them before, has anyone one any idea?
