So I'm not sure what is going on with my body, For the past week I have been feeling kindof slight cramps constantly, recently been getting random headaches, and for the past few days my nipples have been VERY sensitive, on top of that I am 6 days late on my period. Could I be pregnant? I took a cheep 89cent test a little over a week ago but should I take another one in about a week? I got the Nexplanon implant birthcontroll about 3 or 4 months ago so I know periods are irregular but should I be having these symptoms? I have had a friend that had a miscarriage before she even knew she was pregnant while having the implant. What should I do? Is it normal? Also, what do you think about the 89cent test? Are they as effective as the more expincive ones?
