I posted before without any replies, but I am going to try again. This time with a new concern.
I have been on some form of the pill since I was 18 years old (I am 25 now). My periods have always been regular while on the pill, and I have had sex without a condom in the past. I have started using an app on my phone to calculate my period (even though I really don't need it because I know when I get it based on my pill pack) and it has me extremely paranoid because it tells me when I'm supposed to "ovulate" and when I'm "fertile." I know on the pill you don't ovulate but this app still makes me paranoid.
My concern is this: my boyfriend and I have ALWAYS used condoms, but this past month we went without them, for the first time ever, 3 times. According to this app, we had sex two days before I became "fertile" and again on the day I was supposed to "ovulate" and again 4 days later.
I am due for my period either today or tomorrow, possibly Wednesday (it is usually on Tuesday) but I have not had any of the typical PMS symptoms (bloating, cramps, headaches, etc) that I usually get other than extreme moodiness/crying a couple of days ago. I did have urinary frequency a couple weeks ago and went to the doctor and he ruled it as a slight UTI (very barely changed the test color) and gave me 3 days of antibiotics so I thought I was in the clear for it being due to a pregnancy (I started it after the sex w/o a condom). I still feel like I am peeing more than usual, but less than before I started the antibiotic.
I took a pregnancy test yesterday because I had one lying around from a previous scare (was stressed) and it came back negative. Do I have a reason to believe I could be pregnant or am I just stressing out and making myself paranoid?
