my last period was 26/05/10 and started clomid on 28/05/10, cycle days 3-7. i went for a clomid scan on CD 13 and there were two follicles, i also had a bit of brownish spotting that day before the scan, one follicle measuring 20mm and one 18mm. the midwife said to ttc for the next few days, which we did. now yesterday on CD 21 i had a 'gush' of dark red and brown blood which went as quick as it came. my nipples are really tender too. i had irregular periods and never knew when i was ovulating. can anyone help me understand what's happening. is it all the hormones working on me?
