Hi sweetie babe,
it is ok to ov at a later date, whether it is 18 or 19. There is no need to ve it exactly on cd 14. When I was on clomid my ov was around cd 14 or 15 and my cycle was really on the dot. I think the pain you felt on your tummy could be ovulation pain.
Before clomid, I used to feel so bloated , no ovulation, and pain, and had long long cycle. Then I realised that I have not been ovulating. And was told that I have pcos. If you have pcos your ultrascan will show that you have multiple eggs from big to small, all waiting to hatch. As our hormones are not balance, we don't ov but our uterus still get thicker. Therefore we get our period. But in your case, since you ovulation kit showed double line and it was almost the same time as the previous month, I believed that you have ovulated. Anyway, clomid helps ovulation.
Good luck babe and tons and tons of baby dust.
I am on the pills to kick start my period till the end of this week. Have you ever take this type of pills before? Hope you can share your experience.
