Tested too early... Or am I out?

[Sweet5]

I got a positive opk on cd 17 and we had sex the night before and then I got sick so we didn't dtd again.

Today is cd 28 and I tested this afternoon and it was negative
Did I test too early?

Throughout the past week I have felt at times like I was getting my period with slight cramp / bloat and a wet feeling but I get lotion cm.

Is it possible to still get a positive?

Yes, too early! You may not even have ovulated till CD 19 and that puts you 9 DPO. wait till 12 or even 14 days past the latest point you could have ovulated to test.

Atomic, is there still a decent chance that I could have conceived having sex on day 16 and ovulating day 19?

Today is cd 30
Last two months they were 19 and 20 days long. They have been irregular since starting the LE diet but I've never had one this long. I usually ovulate before day 14 so I know I ovulated unusually late this cycle and I feel like she is still coming ... Just later ��

Also, I've read that you are constipated when pregnant and I was with my son. I have not been constipated at all... Is that just a symptom you may or may not have?

[atomic sagebrush]

yes still a decent chance

constipation doesn't always kick in this early. every pg is different
