Sick 🙄🙄

Okay, so my one friend has the flu and pneumonia but I haven't been around him since this weekend. And once we found out me and my roomates continuously clean the apartment. I've had a cough for a few weeks just from recovering being sick from before. I thought yesterday I was starting to come down with something but I couldn't pinpoint what it was. Today after looking over myself I'm pretty sure it just my sinuses are acting up. Last time I went to the doctors (when I had something similar in may for the first time) they said it was just "really bad allergies" and told me stuff to take. And this time around I have been and it seems to be helping! But it still sucks. There's a lot of pressure in my head and I still have that cough but other than that it's really my only symptoms. And the fact that when I cough it "hurts" (more just like a little pressure) in my lower abdomen like where cramps would be. And a few times this morning when I woke up and coughed it made discharge like get "pushed" out of me? But it's my ovulating week and I know there's usually more discharge this week, there has been for me before. I can't remember if this happened last time. But I also worried if it's any sign of pregnancy. I know t sounds crazy bc I'm not sexually active but there was one time over this weekend that I accidentally grazed my boyfriends penis when I was straddling him and felt something and was worried if it was precum if there was any way for it to do this to me. Anyways, I'm pretty sure I'm sick and it's just making me delusional and worry even more but any opinions? Anything I can do to help my headache and nasal drainage?
