Can someone please Explain?!

So it’s been a month since I have had my period. My last period was Dec. 1st and it lasted for 5 days. Flashback to the end of November I had lost a pill and got advised by the doctor to take the 2 pills the next day and not to worry about the days in forward and that I would start earlier like end if December near Christmas because of the pill cutting short. Well I had spotted a few days after my period after that 5 days mark for one day and that was it. Yes me and my husband are sexually active of course lol. I had gotten the flu around the end of the time I was suppose to start and got out on antibiotics which could affect the pill and I never started at the end or even the beginning of January. I started to feel extremely exhausted to where I couldn’t focus and having occasional sharp pains in abdomen and pelvis with light cramps. Well I took 2 home test that were negative and one at the doctor that was also negative. So they checked for thyroid and iron and those came out normal. I stopped my pill about 4 days ago because it was making my symptoms worse to where I was feeling really nauseated and it was an aggravating feeling in the same areas. So of course I expected to spot and the first day it was seldom and very light, second day it was light but as the day went forward it was getting heavier and darker with clumps and doctor told me it was because the pill was clogging and backing it up and making uterus contract, but that it wasn’t my period and that I’m suppose to start beginning or middle of February. So during my spotting I didn’t get those pains and. Now since it’s seeming to go away it’s coming back. I’m having to get ultrasound checked for cysts. Has anyone had cysts with these issues or could I still be pregnant?
