Me and my partner have had sex quite a lot recently. I was ovulating on 3rd - 8th Feb and had sex on 3rd, 4th, 5th and 8th and also before and after. I've been feeling sick, I can't smoke anymore as tastes horrible to me now, getting pains in stomach and lower back, my boobs feel tingly and are itchy, feeling more hungry and also I am more tired than normal. My period is due on 20th Feb, I took a pregnancy test yesterday but came up negative but my partner thinks I'm pregnant still but I don't.
Could I be pregnant?

I can not believe the amount of people who ask this question.

Yes, you could be pregnant. Anytime you engage in sexual intercourse, protection or no protection, you have the possibility of becoming pregnant.

It is far too early for pregnancy symptoms though.

Wait until 14 days after your MISSED period, then take a HPT using your first mornings urine.

How exactly do you know you were ovulating on those particular days? Have you been keeping a Basal Temprature chart?

If you were using any other chart or some cell phone app... its most likely wrong.

Online ovulation charts are good for some people, but not all. So unless you were medically testing for ovulation, then no you do not know if you did or did not.

But of course you could be.

It is too early to have signs and there is no way to tell at this point.

You need to miss a period, and be two week late just to do the first test. So you are testing far to early
