I very much doubt it because you have had your period, although pregnancy will not pick up on a test until about 4 weeks after conception because your HCG levels are not high enough. If your next period doesn't come, then test again.
I Had Sex A Week Before My Period. An I Am Used To Having A 5 Day Period. This Time I Had A 3 Day Period. Could I Be Pregnant? I Took A Test 5 Days After I Had Sex.
By now you probably have answered your own question but I had a period just the same as you had and I am now 7 weeks pregnant. I usually have a 5-6 day period with a bit of heavy bleeding but this time I had a really light 2-3 day period, not even enough to fill up a pad. I totally thought this was my period and went on my way but a week before my next months period I started feeling really sick. I took a home pregnant test and it was positive, then took a blood test and my hcg levels where around 24,000. You very well could be pregnant. Wait it out.
