Ladies my period was supposed to start 4 weeks ago, I’m regular. After the first week late I took a pregnancy test and every week late again. At this point I’m in 4 pregnancy tests and they all come out negative. I forgot to check in when I had sex but I know I didn’t have sex around my ovulating week because my husband was traveling for work. But I did have sex like 3 days or so before starting my ovulating week, so like 6 days before my ovulation day. I’ve been feeling really lazy, tired, less hungry and a lot of headaches and also some sensitivity on my areola/Nipple area. What should I do next?
