Watery blood a week after my period!!!!!!!

Sasha • Pcos-Ttc for 4 years 😪😖😭

So here’s my calendar and you can see when I started and finished my last period and just last night on the 5th of October I had a whole lot of watery discharge then 30 mins later sticky and watery blood came out it was bright pink but I had two medium sized clots in the toilet!!

Now the bloods gone like a brown colour but it’s still a bit thin and watery and I’m only leaking like spotting...

I have pcos and it’s rare for me to have regular periods but for the last 3 months they’ve been regular but this week I’ve been randomly spotting after my period but I just put it down to hormones.

I’m not on contraception as me and My fiancée have been ttc for 5 years..

I’ve lost a bit of weight so that would explain my periods coming back but why would I have watery bright pink blood a week after my period??? I’ve never had this bag I haven’t got anything else except lower back ache more so if I walk too much..

Should I be worried? Is it possible for me to be pregnant? Perhaps it’s ovulation bleeding ? Please help me get some piece of mind..

Not my pics but this is what it’s looked like, the second time it had a small blob of red but this is how it’ looked to me mostly...
