I'm not 100% sure when I'm ovulating. The <a href="https://play.google.com/store/apps/details?id=com.glow.android">glow app</a> is telling me it will start tomorrow however this other trackers I have (pictures below) tell me i have already started. My husband and I were sexually active on Friday and today I have felt horrible, headache, stomach pains, dizziness, fatigues, shaking, nauseated. Isn't it to soon to have any symptoms of pregnancy? I also had spotting the day after intercourse which has NEVER happened! I'm not one to post in these type of forums and just wait it out for myself but I just need some insight! Any advice/opinion is greatly appreciated!!!
