PLEASE READ...I’m worried....🤒😓Ok so someone educated! A little graphic ig...

But I had a few drinks on the 6 of may and my husband and I had intercourse and well things happened. My period was really light the next day which is NOT COMMON! 😳 the next 3 days it was just discharge with pink in it. I’ll was freaking out. I then started experiencing frequent urination and insomnia I kept getting hiccups too. Yesterday morning I felt so nauseas.🤢 I couldnt sleep the night before and I was super emotional crying for no reason really irritable then in the late afternoon early evening I was so Hungry but I couldn’t keep the food down. Today was worse it was a wave all day Constant. I heard people could get pregnant while on their period is this true!!?!?? I went on web md put in the information and the first this was pregnancy and a full bar. The next morning sickness...I’m scared to test. When is the best time?!?
