TTC But unsure of when I will ovulate?

[Alicespring]

I had a miscarriage on Dec 4th with retained products so I didn't get a negative pregnancy test until last Tuesday (21/1) while having a period. Before the misscarriage I had heavy periods with a very regular 27 day cycle and my periods never lasted longer than 4days. However since the misscarriage my first period lasted ten days so now I'm unsure about how to work out when I will ovulate. Will it be the usual day 14 even though I only stopped bleeding 4 days prior?
I've got some OPK and they are showing a faint line but I know that is negative.
Desperate to start trying again!

Look up signs of ovulation, like Temperature, vaginal mucous. Not many people have text book cycles so it’s better to know how to spot it yourself

And so sorry for your loss

I would invest in the flashy smiley face clear blue tests. There's no doubt then as to when you are your mist fertile

Thank you both.... unfortunately it looks like my period has started back up again today so my cycle must just be really messed up. So frustrating!
