Hellllllo Ladies. AF is currently 15 days late.. Ive taken two of the CVS brand hpt and they were both negative. I took the first one a week after my missed period date and the second 4 days after the first one. My period was due on the 16th. I had sex unprotected, on april 1st, 8th and 15th. According to my app i use to track my periods. I had a high chance of pregnancy on the 1st. My symptoms? Well, not being able to sleep, Im having to pee, ALOT. (I read somewhere that hormones during the beginning of a pregnancy will make you pee.) Ive gotten small cramps here and there, not that bad. Maybe three times a day ill cramp for like a minute then stop. But like 2 weeks ago i do recall my discharge (sorry tmi) was thick and kinda pinkish brown for about a day or so then it turned into just a watery substance and it hasnt stopped since. Could I be pregnant? I haven't been to the doctor because i have a check up next month anyways. Any idea?
