Hi, I have irregular periods and have been trying to conceive my second child for couple of months. I thought I could be pregnant but after 6 weeks between periods (& 2 negative home tests) I had a heavy 5 day period which ended on 24th July. On 26th July we had unprotected sex then on 30th I experienced what I thought to be motion sickness as I was the passenger in a car for 2 hours & had to stop twice but wasn't actually sick, however this feeling of nausea has remained now for 2 days. Today I have had lower right sided abominable pains, more like dull aches though than pains. I'm also urinating more frequently & feel like I have a heightened sense of smell. Is it possible that I could be pregnant & experiencing symptoms already or is it not possible & probably in my mind & coincidence? Also could it be a pregnancy a previous attempt during the 6 week gap in between periods or is this not possible? I'm sorry if this makes no sense whatsoever.
