(I started my period on the 28th of February and it ended on the 5th of March) On the 11th of march I had unprotected sex with my boyfriend and he finished inside of me and on the 12th I started to spot and have these weird cramps in my uterus and I felt bloated the next day I started to spot and my breast started to hurt and every time I woke up I felt sick. A week later I went to the doctor and she said that I wasn't pregnant and I don't have any STD's or STI's. I have be spotting from the 12th of March until the 21st of March and on the 22nd it turned from spotting to this dark red period and on the 25th it turned from a dark red period to this white pink brownish color. ( I started ovulating on the 15th of March)

How do you know you ovulated on March 15th? Ovulation tests... Basal Temp chart? Wild guesses?

Chicken entrails.

So you had your period at the end of march? If you're concerned at this point take a HPT you should show positive if you had gotten pregnant in feb.

My calendar

First, pregnancy symptoms don't happen a day after intercourse. You're not even pregnant a day after, it takes many days for the sperm to reach the egg, then the egg has to travel and implant in the uterus. It's not instant.

You would not have sore breasts due to pregnancy, or nausea due to pregnancy, a day after intercourse. A test done a week after sex, would not indicate pregnancy, as you wouldn't even be pregnant at that time. At 7 days the sperm is still traveling to the egg, pregnancy hasn't occurred at that time. So a test done at that time would not show pregnancy. It doesn't mean you're not pregnant, it just means it's too early to test.

You said you had a period on March 22. Once pregnant, a woman does not get a period. A woman may have spotting that she mistakes for a period, but periods stop once you are pregnant.

If you feel you may be pregnant, now is the time to test. Get a home pregnancy test, and test using first morning urine. If that test is negative, wait for your next period and if you miss it, test again.

Also, unless you're testing using basal temperature for at least 6 months to track ovulation, your calendar is useless. Online calendars and apps are a guess. All women are different. The only way to know for sure when you ovulate is by using basal temperature readings for at least 6 months. One year is better. So don't rely on your calendar unless you're actually physically tracking ovulation.

Good luck.
