Early + OPK?!

Emily
Hey guys! So I'm on my 2nd round of clomid (first was 50mg CD 3-7) and this round is 100mg CD 3-7. On CD 9 I had just some brown-ish discharge from my period (sorry if TMI) and also got a + OPK. I also got a positive CD 10 and 11 (today). In the past when I've tracked my ovulation I normally haven't gotten + tests until CD 15/16. Anyone heard of either ovulating earlier with clomid OR false positives? Need some advice! Thanks guys!
