I need help!!!!

Ok ladies idk what’s wrong with me at this point! so last week I had a “period” I say it like that bc idk if it was or not but it lasted for 3 days and was nothing but dark blood and I didn’t even fill up a tampon in a day. I’ve been getting morning sickness, feeling tired, dizzy, bloated, nauseous, Having insomnia, loosing breath quickly, headaches, back aches, food cravings, hot flashes and mood swings for over a month now. I literally burst out into tears yesterday and I have no clue why. I took a test I believe a day after my “period” and it said negative. I’ve been having slight cramps and backaches on and off here recently and today I spotted my next period isn’t due for another 3 weeks and I just ended my last period like a week ago. I had sex on the 21st of March(Day of Ovulation) got a light period on the 5th-7th of April nothing but old blood and didn’t fill up a tampon all day, had sex on the 20th of April and May 1st and got another light period on the 7th-10th of May nothing but old blood and still didn’t fill up a tampon. On the 11-13 of April I didn’t take the pill because I was out of town and ran out of my other pack after finishing the sugar pills. My normal periods I fill up at least 2-3 tampons a day and it usually lasts for 5 days and have heavy cramps but not my last two periods my cramps have been very light and it’s been nothing but old blood. No I don’t let him finish in me but we only rely on the pill. What’s going on none of this is adding up??? Thoughts!!
