Ttc after iud

Had it taken out on 30th Oct (day 17/30).

Very very heavy bleeding roughly 1st Nov (day 19/30) till 8th Nov (day 27/30).

Then none/small spotting until the day my period was due on 12th Oct when I had spotting of bright red blood a very very light bleeding for about 10hours.

I'm so unsure what is happening!!!! We did have *half of* sex about 2 weeks ago unprotected. When am I due to ovulate? Was the bleeding early my period? :( I have 1 child that we only TTC for a month and I never had a big red line on ovulation tests.

I'm getting these lines since Wednesday.. and took pregnancy test today and maybe there's a very very faint lime but don't think so.. :( help? When am I ovulating? My discharge is clear etc.
