I am so confused. My period cycle is about 29-30 days. I had my last 2 periods (Aug 17th and Sept 24th). It was late by few days for the first time last month. Anyhow, my husband and I just decided to go for a baby and we had an intercourse about 18 days and 12 days ago. Past few days I been experiencing fatigue, abdominal pain in the lower left side, unable to sleep at night (as in I can't fall asleep at all although am so tired and sleepy) and loose bowel movement 3 times a day.

I felt light feverish and weird bitter taste in the back of my mouth, slight nausea while riding bus in the morning (which I never had before). I tired to research and realized that breast should be tender and all, I usually get that with my period but not this time, I've no signs of breast ache or pain.

Could this be early pregnancy signs? I just ordered the ovulation kit thinking am going to track it as of next month but all these makes me wonder if am pregnant already. Either way, can can someone ans me how long do I have to wait to take a pregnancy test at home. Can I try it today? Or do I have to wait till I pass the period date?
I'll be receiving my pregnancy test strips today so I am going to check it but some please let me know when is the best time to test if missed period so if the test is (-)ve I'll test once again.
