On 9.02 I had protected sex, but the sex was forced. For a month now, I've been under a lot of stress related to work and the constant lack of time. Sometime in the middle of February, I started to have stomach problems, I didn't want to eat anything, I was sick at times, hence I started to worry about pregnancy. On February 29th, the day of my expected period, I took a pregnancy test in the morning, it came out negative, and later in the day I got my period normally. The period was typical, strong cramps, clots, etc. Unfortunately, these symptoms associated with stomach pain and nausea have remained. I'm stressed all the time. Yesterday, i.e. February 11th, 31 days after intercourse, I took 2 pregnancy tests in the morning from the urine of two companies. Both also came out negative. Is there a chance that I could be pregnant? Should I repeat the tests? I'm very stressed out by this whole situation and it exhausts me mentally.
