Help!, Sign of Ovulation or just Bad timing?

[Hazybaby84]

Can someone please tell me if they have experienced the same. To clarify let me start from the beginning. Me and my partner decided to look into ttc number two at the end of this year, as unfortunately I had a ectopic pregnancy at the end of may and didn't feel quite readt to try again. Well me and my partner done the deed Sunday morning and our only form of bc at the moment (condoms), actually split. I was due to O yesterday according to the calendar based on my 25 day regular as clock work cycle. Now to my above question, I was perfectly fine till 4pm approx yesterday, now my nose is really congested and I have a sore throat. It seems to have come from nowhere but it seems a bit odd that I would suddenly get it on the day my calander says I should of O'd. So now I am wondering if it is do with that or if it has just been bad timing and I just have a really bad cold coming on. X x
