Pregnancy symptoms after short bleed post ovulation

Did anyone have a short bleed at the time their period was due and found out they were pregnant shortly after?

My cycles are anywhere between 30-40 days long so i don't know my timing of periods or ovulation.

I did have a blood test that showed positive ovulation on CD30 and Hubby was home during that week so we had our fingers crossed. CD38-41 I had minor spotting on and off. CD42 i had medium-heavy bleeding for the day and then 2 days of light to medium bleeding. My period is normally 5-6 days and consists of 3 full days of heavy bleeding.

For the last 4 days I've felt exhausted, nauseous, headache, peeing often and can't think about food. (Haven't got a pg test at home to do and haven't been out to grab one).

Did anyone else go through something similar and actually be pregnant?
