Could I be pregnant?

[Potentialmama23]

So my boyfriend and I had intercouse 3 times last month on the 14th, 16th, and 17th of May which was on the same week my period was suppose to start. I had a lot of discharge for a good two weeks & I'm currently having a good amount of discharge. My time of the month (my M cycle) was suppose to start on the 16th of May BUT it didn't, I ended up bleeding brown and very light for four days and my M cycle started on the 20th - 25th of May. According to my Flo app, My ovulation day was suppose to be on the 4th of June.

My boyfriend and I had intercourse again on the 31st of May and on the 4th of June. On June 2nd - till now which is the 12th of June, and my nipples are extremely sore. As the days go by, my breasts feel more heavy and are starting to feel more sore all over. Starting on June 2nd, I started to feel nauseous. One morning I had a cookie & wanted to throw it back up and it continued with certain foods. I'm not as hungry as I normally am. I get nauseous when I eat certain things that I normally love eating. I had a slushee from sonic & all I could taste was this sink water taste which it never tasted like that before. I also had cramps from the 2nd - 4th of June, I'm assuming the cramps is from my ovulation day. I started getting cramps again starting yesterday to today! I've also been really sensitive and emotional. I've also been peeing a lot! I use to pee like 2-3 times a day but now it's like 5-7 times a day & I hardly drink anything.

What is really puzzling me is that my periods are normally heavy, I have horrible cramps, back pain, and occasionally sore nipples but maybe for like a few hours or a day. All of this is extremely different for me. When my M cycle was suppose to start last month, it bled brown and I didn't have any cramps or period symptoms. From the 2nd till now, I've been emotional, breasts are sore & heavy (I've noticed a little more veins as well), I've been cramping, bloated, nauseous, fatigue & I have a lot of saliva. My next M cycle is suppose to start on the 16th - 21st of June according to my period app. I took a few pregnancy tests which I think was a little too soon which is why they came out negative. I know as a woman, our body changes over time but I've never had sore nipple for more than a day. I'm the type of person who NEVER throws up or feels nauseous. The last time I threw up was because I eat enough carbs with my medication for my acne years ago. Other than that, I don't think I threw up since I was a kid. On another note, I've always experienced period symptoms a week & 1/2 before my period starts & my period always come in STRONG but last months was way off & hardly had no symptoms. Could I potentially be pregnant? Thank you everyone who has helped in the future and for your input!
