Could I be pregnant??

Me and my boy friend had sex June 30th, he ejaculated in me. I own a 30 day cycle it lasts 5-7 days. I got "maybe" my menstrual July 11th and it's be very irregular which isn't usual to me. I had for 4 days and its been on and sour and the first day was regular but it has gotten lighter. I've be having headaches and dizziness, weird stomach pains, stern pains, and a pain in my chest that feels similar to heartburn for a couple days, I never felt like this before not even on my menstruation. Could I be pregnant?

I just don't surmise most ppl get symptoms that early-- Take a test if you think you missed your AF. Source(s): 5 weeks
yes you can ovulate at any time, and you said your cycles are 18 days long? that seems short.
Answers:    That would mean that your prior menstrual interval was around the 12th of June, which--assuming you ovulate mid-cycle--would mean you probably ovulated around the 27th of June. Unless you ovulated 3 days later (ovulating on Cycle Day 17 next to a 13 day Luteal Phase), I would say the probability of pregnancy isn't very high-ranking. Plus the fact that you got your period already, even if it be a bit stranger than you would normally expect would lead me to believe that you are not pregnant.

If you had your everyday period the first day, even if it got lighter during the following days (this is completely typical, by the way) means that this is your period. Plus it's lasted 4 days already-if it be implantation bleeding it would have been very night light, lasting between 1.5-3 days at most.

However, if you're still in doubt, try testing contained by about a week. Good luck.
