I’m 45 and partner is 31.

Any advice, I’m in Australia.

Also can anybody make anything of this; Also, had a sex session 2hrs no protection 3 days after expected ovulation. Could I be possibly pregnant?

Normal period is every 4 weeks. This time I got my period a week earlier than usual, so my cycle was this; 21-26/11/17 - period

2/12/17 - ovulation

5/12/17 - 2hr sex session no protection, withdrawal method

13-17/12/17 - period

24-25/12/17 - cramping, no stretchy cm, creamy white no smell, possible ovulation

25-26/12/17 - predicted ovulation
