TTC 2nd baby and confused!

Hi ladies

I am incredibly lucky as I fell pregnant with our son (now almost 2) whilst on the pill. My pregnancy was easy and I feel bless.

We've now decided to stop contraception (condoms so being having normal periods) and TTC baby number 2 but now my periods etc have gone haywire. I'm not used to <a href="https://play.google.com/store/apps/details?id=com.glow.android">tracking ovulation</a> etc as we weren't even trying with our first but now it's seriously stressing me out.

I had my period 13th-18th then sex 26th. Afterwards I was convinced I was pregnant as I felt different and as I did with my son. On the 7th I had a dark brown (sorry, TMI) bleed which last about 30 minutes. I thought this may have been implantation but now on the 26th having a very heavy and painful period.

I am so confused as this is out of synch and I'm usually so regular!!

If anyone is able to shed some light on the their thoughts on the above (and in particulate the blows on the 7th) I would be grateful.

Many thanks,

Stressed-out Mumma xx
