I got my period on march 1st. I had sex with my boyfriend on march 9th and began ovulating on march 12. My boyfriend wore a spermicide condom during intercourse and I finished him off with a blowjob. Afterwards, he inserted himself into me but there was no penetration. What are the chances I could be pregnant?

There is always a possibility, however remote.

He either inserted or he did not, if he inserted there was penetration.

But yes there is a chance, no birth control is 100 percent.

Also how do you know ovulation, since it really does not always follow a number of days, so online systems, that do not use body checks like temp, are not corrent many times

My discharge is thicker and I can feel it, I usually ovulate 12-15 days after my period

The sex three days before ovulation is the correct timing, since it takes two or three days for sperm to reach, So the day of sex increases the chance..
