The first time I had sex after I took the PT was March 29. My partner and I have had intercourse a few times especially on my most turtle days (April 4/5) the last couple days I have been dizzy, very fatigue, and even had heartburn for the first time in a long time last night and today. I already bought a cheap PT but I'm not sure if it is to early to test yet considering I "should" start on the 19. Feel free to comment please!
