So I have not had my period in a while, I have been having menstral cramps which is unusual since I have not gotten my period, I did spot light pink and a week later spotted brown and pink. I have been nauseous and super tired, and my nipples are super sensitive, I feel like I have bloated, like my pants are getting tight on me, I took a pee testa do it says no. Any ideas or suggestions.? Oh, and sometimes I feel like at the bottom of my stomach it is having muscle spasms, like something is pulling up in a way and letting go. I think it could be twingles. I put my information (last period day) in on glow nature and it says I am 7 weeks and 4 days.
