First cycle

Chelsea
Anyone else had really bizarre ovulation after their first period after first af? I'm pretty sure I ovulated as soon as my first 'period' finished after my MC (7th Feb) and my first 'af' started on the 18th march lasted three days and now today I think I got a faint positive? Bizzare? Possible? Experiences? Also had my HGC tested he day my period ended at the HGC level was at 3??
